3 on this page, please see page 1 and 2. Surface Preparation Application Materials Do not assume that the surface is clean. All substrates must be cleaned. The surface location and condition determines which preparation method to use. 3MTM surface preparation system Unpainted Exterior 1 inch masking tape 1. Clean the surface with a solvent such as 3M Edge sealers Surface Preparation System or isopropyl alcohol, and wipe dry with clean lint free rags. Do not Tools allow the solvent to evaporate before wiping. 6 to 8 foot (1.8 to 2.4 m) table 8 foot (3 m) measuring tape Metal straight edge Clean lint free rags 3M PA-1 Plastic Applicator (gold) Low friction sleeve 3M RBA-1 Rivet Brush Precision cutting tool Key Steps for a Good Application 1. Review the application instructions before starting and read the Application section in the applicable Product Bulletin for special application requirements for the type of film being applied. 2. Apply all film within 2 years of receipt, and printed or imaged film within 1 year. 3. Apply the film only if the air and surface temperatures are within the range of 10 to 38 C (50 to 100 F). 4. Make sure the surface is clean. Even newly finished surfaces must be cleaned before application. 5. Use a sharp PA-1 applicator. 6. Use firm squeegee pressure with overlapping strokes. 7. Overlap adjacent pieces by at least 5 mm (1/4 inch), but not more than 10 mm (1/2 inch). 8. Remove the premask tape at a 180 degree angle. 9. Work out all air bubbles by pushing the air out to the nearest edge or perforation. 10. Work the film down into irregular areas with a rivet brush. 11. Re-squeegee all edges and overlaps after the premask is removed. 12. Edge seal required edges. 13. Cut the film over all substrate seams, and then edge seal. Temperature Requirements Apply the film only if the air and surface temperatures are within the range of 10 to 38 C (50 to 100 F). Page 3 of Repeat until you are sure all contaminants are removed. Primed Exterior 1. Sand and prepare the final primer coat according to the paint manufacturer s directions. 2. Clean the surface with a solvent such as 3M Surface Preparation System or isopropyl alcohol and wipe dry with clean lint free rags. Do not allow the solvent to evaporate before wiping. Topcoated Exterior 1. Before applying the graphics to a freshly painted surface, the paint must be cured for the time recommended by the paint manufacturer. Special attention must be given to two-part polyurethane paint systems and clear coats because these outgas as they cure. The outgassing will cause bubbling of the graphic. A minimum of 5 days curing time at 21 C (70 F) or above is generally required before outgassing decreases to a point where bubbles are no longer detectable. 2. Freshly painted surfaces must be cleaned. Clean the surface with a solvent such as 3M surface preparation system or isopropyl alcohol and wipe dry with clean lint free rags. Do not allow the solvent to evaporate before wiping.

4 on this page, please see page 1 and 2. Registration 1. Position the graphic on the surface following the airplane manufacturer s requirements. 2. Make registration marks on the surface to position the top or side edge of the graphic. See Figure 1. Important Note When making registration marks, use a type of marker approved by the aircraft manufacturer for use on the skin of the aircraft, except do not use chalk lines, china markers or grease pencils, which prevent the adhesive from bonding to the surface. Applying Large Graphics There are several methods for applying large graphics. Use the one that works for you. These are some general suggestions. 1. Choose the method that puts the masking tape hinge perpendicular to the longest dimension of the graphic. The Center Hinge Method works well for stripes less than 305 mm (12 inches) wide. See page On a curved surface, put the hinge so that when the graphic is folded back it wrinkles as little as possible. 3. Use the Split Liner Method when masking tape is not available or for horizontal applications. See page Any application method works with a scored liner. With a double scored liner, remove the liner between the scored lines and apply the graphic using the Split Liner Method. See page 6. Top Horizontal Hinge Method 1. Tape the graphic in place with small pieces of masking tape. Make a hinge by putting a piece of 51 or 76 mm (2 or 3 inch) masking tape over the top edge. See Figure 4. Figure 1. Registration 3. Tack the graphic in place with thumb pressure in the upper corners. 4. Hold the rest of the graphic away from the surface to avoid pre-adhesion. See Figure 3. Using firm, initial squeegee pressure, begin at the center of the graphic and work outward in all directions. Figure 4. Making a Hinge 2. Pull the graphic above the top hinge and peel back the liner a few inches. See Figure 5. Figure 3. Holding the Graphic to Prevent Pre-adhesion 5. To avoid wrinkles, release the tack points before squeegeeing over them. Figure 5. Peeling Back the Liner Page 4 of 12

5 3. Hold the graphic away from the surface with one hand. With firm overlapping squeegee strokes, begin at the top center. Peel the liner back a few inches at a time. Allow the adhesive to touch only as pressure is applied. Work down and out to each edge. See Figure 6. Figure 8. Cutting Off the Liner 3. Remove the tape hinge. See Figure 9. Figure 6. Squeegeeing the Graphic 4. Remove the tape hinge and re-squeegee the edges. Center Hinge Method 1. Tape the graphic in place with small pieces of masking tape. Make a hinge by putting a piece of 1 or 2 inch (25 or 51 mm) masking tape through the center of the graphic either vertically or horizontally. The best place to put the tape is perpendicular to the longest dimension of the graphic. See Figure 7. Figure 9. Remove the Tape Hinge 4. Fold over the other side of the graphic, remove the liner, and squeegee the film down using the same firm overlapping strokes used in Step 2. See Figure 10. Figure 7. Making a Center Hinge 2. Fold half the graphic back over the hinge. Peel the liner off the graphic as far back as the tape hinge. Cut the liner along the hinge and discard. Hold the graphic away from the surface with one hand. With firm overlapping squeegee strokes, begin in the center and work the shortest distance to the edge. See Figure 8. When cutting the liner, use care not to damage the skin of the aircraft. Use rather a snitty. Figure 10. Squeegeeing the Graphic Split Liner Method 1. Place the graphic face down on a flat surface. Peel back the liner and cut off about 1/3 of the liner. See Figure 11. Page 5 of 12

6 Figure 14. Applying the Rest of the Graphic Figure 11. Removing a Third of the Liner 2. Move the liner so that 25 to 51 mm (1 to 2 inches) of the adhesive is exposed. Gently squeegee the liner back down with the plastic side next to the adhesive. See Figure 12. Applying Large Pre-Spaced Graphics 1. Position the graphic on the aircraft and tape in place using the Horizontal Top Hinge Method as discussed on page 5. See Figure 18. Figure 12. Moving the Liner 3. Position the graphic on the aircraft. Squeegee the area of exposed adhesive. This will now act as a hinge. Figure 18. Making a Top Hinge 2. Create an independent top hinge for each letter or number by cutting through the premask and into the masking tape. See Figure 19. Figure 13. Moving the Liner 4. Remove the liner and apply the rest of the graphic just as you did in Step 2 of the Center Hinge Method. See Figure 14. Figure 19. Creating a Top Hinge for Each Character 3. Remove the liner and squeegee each letter or number separately using firm overlapping strokes. Be sure to squeegee the areas where there is just premask. This helps prevent wrinkles and misalignment. Page 6 of 12

7 on this page, please see page 1. Finishing Steps 1. Remove the premask by pulling it back on itself at a 180 degree angle. Squeegee the film wherever it is not firmly bonded to the surface. Using a felt squeegee or SA-1 low friction sleeve on a plastic squeegee will help to prevent scratching of the film surface. Re-squeegee all edges and overlaps using very firm pressure. 2. Cut the graphic on all substrate seams with a razor blade (in a holder) or similar cutting tool. Re-squeegee the edges or use a rivet brush. 3. Look for bubbles in the flat areas. To remove a bubble, puncture it at one end with a pin or round pointed tool; never use a razor blade. Move toward the hole with a finger and press out the trapped air. See Figure Work the film down into the irregular areas with a rivet brush. These areas must be edge sealed: Leading edges of the film. Edges where the graphic has been cut for doors, access panels and similar items. Any cut out repair areas where the film overlaps film. Apply the edge sealer with 1 cm brush. Place the brush so that it covers both the aircraft surface and film equally. Pull it along the edge in a smooth, continuous motion. Storage of Edge Sealers Edge sealers should be stored in a cool, dry place and should be used within one year of data of purchase. Containers should be tightly capped after each use. Film Overlaps Vertical Overlaps Apply the first piece on the rear of the aircraft. The next piece must overlap the first one about 5 mm, but not more than 10 mm. Horizontal Overlaps Apply the lower piece first. The next piece must overlap the lower one Figure 20. Puncturing Bubbles Edge Sealing When using edge sealer, an improper application, failing to allow the edge sealer to cure properly, or incompatibility with the substrate may result in a serious product failure, including the graphics lifting off the surface. Edge sealing helps to reduce film abrasion due to wind and rain. The sealer also improves the film s resistance to fluids. Use the edge sealer specified below: For film VS7704 use edge sealer 4150S or AKZO Aerodur UVR For film VS7322, use edge sealer 3950 or AKZO Aerodur UVR. on this page, please see page 1 and 2. Maintenance Inspection Graphics should be periodically inspected for lifted, frayed or torn areas. Repair damaged areas immediately. Please contact 3M Technical Service at / to report any such performance problems. Cleaning Graphics damaged by improper cleaning are not covered by the 3M warranty. Use a wet cleaner suitable for high quality painted surfaces. The cleaner must be: Non-abrasive. Neither highly acidic, less than ph 3, nor highly alkaline, greater than ph 11. Free of strong aromatic solvents, chlorinated solvents and ketone containing solvents, like acetone and methyl ethyl ketone. Page 7 of 12

8 Repairing Damaged Areas Before handling any chemical products, always read the container label and the MSDS. 1. Mask around the damaged area with 5 cm (2 inch) masking tape. This will keep the primer on the damaged area. It is not necessary to mask the windows. 2. Remove lifted, frayed, or torn film. 3. Cut a replacement patch 6 mm +/- 3 mm (1/4 inch +/- 1/8 inch) larger than the repair area. 4. Clean the area thoroughly with isopropyl alcohol. 5. Apply the film following the usual application method. 6. Edge seal all the edges with the recommended edge sealer. See the Edge Sealing section to the left Removal of Films VS7704 When using any equipment, always follow the manufacturers instructions for safe operation. Solvents may ignite near heat or open flame. Do not use heat sources near solvents. Failure to avoid the use of heat sources near solvents can cause flash fire. There several methods that can be used to remove film. The methods provided here are listed in the order of ease of use. Typically, we recommend using the easiest method. However, you may need to use one of the other methods, depending on graphic size, condition and length of service use. Heat Gun Removal Method Important Note Before using a heat gun, consult the aircraft manufacturer regarding the maximum temperature to which the skin of the aircraft can be heated without affecting surface integrity. Material that has not been on the aircraft too long may be removed by using an industrial heat gun. Heat one corner of the graphic. Slide a razor blade (in a blade holder) or knife edge under the corner to loosen the graphic. Be careful not to damage the substrate. Slowly pull the film at an angle less than 90 degrees and heat the area immediately ahead. Steam Removal Method Some customers have indicated that a professional steaming unit, such as a wallpaper steamer (Bosch PTL1), may be used to soften the film, before removing it. This procedure may be used on a customer test-and-approve basis. Follow the instructions provided by the manufacturer of the steaming unit. Once softened, slowly pull the film at an angle less than 90 degrees to maximize the amount of adhesive that is removed. Page 8 of 12

9 on this page, please see page 1 and 2. Chemical Removal Methods 3M Graphic Remover System (where available) Where the product is available, 3M Graphic Remover System can be used to remove film VS7704. Please consult your 3M Sales or Technical Service Representative for details. Paint Stripper The same method used to strip paint from the aircraft will also remove aircraft film. Primer and Tape In this method, an adhesive primer is applied and then a tape. The tape strengthens the film and makes it easier to remove. It works better to have two people working together removing one stripe at a time. The following materials, tools, temperature and procedure refer to the Primer and Tape method. Primer and Tape Removal Procedure Before handling any chemical products, always read the container label and the MSDS. 1. Break the film loose from any edge sealer using a sharp, hard plastic tool. 2. It may be possible to skip the priming step and still remove the film by applying Scotch box sealing tape 375 to aircraft exterior graphic films. Test the film by going through Steps 6 to 10 without putting the primer down. 3. Begin at the aft at an exposed leading edge, like a door. With a paint roller, roll the primer on the graphic in a thin even coat. Work toward the fore about eight feet. Stop at a graphic overlap. 4. Allow the adhesive to dry 10 minutes, or until it is tacky to the touch. 5. Within 60 minutes after coating the primer, start at the back section applying the tape 375. Materials Needed Scotch Masking Tape, 51 mm (2 inch) 6. Put tape 375 perpendicular to the long dimension 3M Fastbond Adhesive 30NF of graphic with a PA-1 plastic applicator. Work Scotch Box Sealing Tape 375, 101 mm (4 inch) methodically from the top down. Carefully squeegee out all the air between tape 375 and the Cleaners and Removers primer. - 3M Adhesive Remover 8908, or - 3M Natural Cleaner, or - 3M Stripe Remover 8907, or - 3M Citrus Base Industrial Cleaner Tools Needed Paint roller Paint tray Utility knife Blade holder and single edge razor blades Hard plastic scraper 3M PA-1 plastic applicator (gold or blue) 76 to 101 mm (3 to 4 inch) diameter PVC tube with handle Note: All 3M brand and Scotch brand products are available from 3M Commercial Graphics Division Temperature Requirements For the best results, work when the air and surface temperatures are 20 to 32 C (60 to 90 F). 7. Continue applying tape overlapping each section from the aft to the fore over the rest of the primed area. 8. Start at the aft of the primed and taped section. Carefully lift the trailing edge. Pull the taped graphic at an angle. The angle between the aircraft skin and the taped section should be less than 90 degrees. Work in the direction of the longest dimension of the graphic section. 9. When a 152 mm (6 inch) piece has been removed, attach it to a 101 mm (4 inch) diameter PVC tube. Twist the tube slowly forward on the graphic. The film should begin to roll onto the tube and to remove from the side of the aircraft. 10. Watch the adhesive side of the graphic for tears or adhesive splitting. If the graphic tears, lift the torn flap and stick it to the remover tape and the PVC tube. If the adhesive splits, change the pulling angle and speed. 11. Use an adhesive remover or any other airline approved solvent to remove any adhesive left behind. After using the adhesive remover, clean the surface with isopropyl alcohol. Page 9 of 12

10 Removal of Film VS7322 on this page, please see page 1 and 2. When using any equipment, always follow the manufacturers instructions for safe operation. Solvents may ignite near heat or open flame. Do not use heat sources near solvents. Failure to avoid the use of heat sources near solvents can cause flash fire. Steam Removal Method Some customers have indicated that a professional steaming unit, such as a wallpaper steamer, may be used to soften the film, before removing it. This procedure may be used on a customer test-and-approve basis. Follow the instructions provided by the manufacturer of the steaming unit. Once softened, slowly pull the film at an angle less than 90 degrees to maximize the amount of adhesive that is removed. Heat Gun Removal First try to remove the film with an industrial heat gun. Film that has not been on the aircraft too long may be removed this way. Heat the corner of the graphic. Slide a razor blade (in a blade holder), or a knife edge, under the corner to loosen the graphic. Be careful not to damage the substrate. Slowly pull the film at an angle less than 90 degrees, and then heat the area immediately ahead. Paint Stripper Removal The same method used to strip paint from the aircraft may be used to remove film VS7322.

11 Plastic applicator Rivet brush Plastic squeeze bottle or trigger-type bottle Appropriate safety equipment. See the MSDS for recommendations. 4. Be sure you have all the required equipment; see Equipment List on page 13. Use all recommended safety procedures including the wearing of unvented goggles and appropriate gloves. 5. Clean the surface and film with detergent and water. Dry the surface thoroughly before proceeding. Removal Procedure 6. To minimize cleanup of film remover R-221, one of the following two methods should be used: Before handling any chemical products, always read the container label and the MSDS. When using any equipment, always follow the manufacturers instructions for safe operation. Solvents may ignite near heat or open flame. Do not use heat sources near solvents. Failure to avoid the use of heat sources near solvents can cause flash fire. 1. Film remover R-221 and adhesive remover R-231 is a system for removing film VS7322 only. If you are unsure of what type of film you are trying to remove, follow the Heat Removal Method or Paint Stripper Removal Method on page 12, but attempt to remove only a small piece of the film. If adhesive residue exceeds approximately 25 percent after the film has been removed, this removal system is NOT recommended for use. 2. Make certain that the surface temperature is at least 10 C (50 F). If it is 29 C (85 F) or above, move the vehicle to a shaded area. 3. Check for possible paint damage. a. Using a paint brush or sponge-type roller, thoroughly wet a small area of the painted surface with film remover R-221. b. Allow the remover to dry for at least 15 minutes. If the ambient temperature is below 21 C (70 F), longer drying time is required; see Drying Time Requirements. c. Peel the dried film remover from the painted surface. d. Check for paint or substrate damage. If any occurs, the remover system is specifically NOT RECOMMENDED. a. Mask the surface around the film and make a drip trough with masking tape or cardboard to prevent residue from dripping onto surfaces around the film. b. Spray the surface around the edge of the film with a commercially-available release agent, such as vegetable cooking spray. Form a drip trough with masking tape or cardboard along the bottom to prevent residue dripping onto the surface below the film. Care should be taken to ensure that the release agent is not sprayed onto the graphic which is to be removed. Any release agent accidentally sprayed onto the graphic must be wiped off. Note: Film remover R-221 is extremely difficult to remove from weathered paint; therefore, it is imperative that the surface around the graphic be masked off or sprayed with a release agent. 7. Using a paint brush or roller, thoroughly coat the graphic film remover R-221. Keep the container covered when not in use to prevent rapid evaporation of solvent. 8. Allow film remover R-221 to dry for at least 15 minutes after application. Cooler temperatures require additional drying time. Drying Time Requirements for Film Remover R-221 Temperature Approximate Drying Time 27 C (80 F) minutes 21 C (70 F) minutes 16 C (60 F) minutes 10 C (50 F) minutes or longer 9. Test for removability by grasping a corner of the film and pulling from the surface at less than a 90 degree angle with gentle/moderate force. 10. The film should stretch like rubber while being removed; if it is brittle, stop, apply a second coat, let dry and proceed with the removal. 11. When the film has been completely removed, pull off the masking tape but leave the drip trough. Page 11 of 12

12 12. Fill a squeeze or trigger-type bottle with adhesive remover R-231. Squirt this liquid in 1 square foot sections onto any adhesive residue remaining. Allow the liquid to penetrate for at least 30 seconds, but not longer than 60 seconds. 13. Remove the adhesive by scraping with a plastic applicator or rivet brush. Once loosened, wipe the residue with a cloth saturated with adhesive remover. Repeat these steps if necessary. 14. Remove the drip trough. Clean the entire surface with a solvent wipe, followed by a wash with detergent and water. Dry the surface. 15. Failure to properly wash and remove all excess adhesive remover will adversely affect the adhesion of new graphics applied to the surface. Note: If new graphics are to be applied, the surface must be solvent wiped following the procedures outlined in Instruction Bulletin Disposal of Waste Adhesive or film removers, and solvent wipes or film wetter with the removers, should be incinerated in a permitted hazardous waste incinerator. Since regulations vary, consult the applicable regulations or authorities before disposal.
