Plastics and glass substrates were cleansed with isopropyl alcohol (IPA) wipes; metal substrates were abraded with 150-grit sandpaper and cleansed with methyl ethyl ketone (MEK) wipes. All bonds were allowed to cure for a minimum of 48 hours at 73°F (23°C) before tested. Data were collected using a Sintech 5GL Mechanical Tester with the 2000-lb or 5000-lb load cells.

Suggested Substrates Note: The following suggestions are based on laboratory tests on typical grades of the listed substrates. Because of the many combinations of process aids and additives that are used with plastic substrates, the user is responsible for determining whether 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8005 is appropriate for a given application. Potential Primary Surfaces Polypropylene (PP) Polyethylene (PE, HDPE, LDPE) Potential Secondary Surfaces Fiber Reinforced Plastic (FRP) Polycarbonate (PC) Wood Aluminum Glass Thermoplastic Elastomers (TPE) Not Recommended Surfaces Inconsistent results have been exhibited with substrates that contain oils and anti-stats.

Hand mixing is not recommended and may result in unpredictable results. 1) Apply adhesive to clean, dry substrates, which are free of loose paint, oxide films, oils, dust, mold release agents and all other surface contaminants. See the Surface Preparation section for specific substrate preparation methods. 45 ml Cartridge: Place duo-pak cartridge in EPX applicator. Twist to remove cap. Dispense and discard a small amount of adhesive to assure even ratio and free flow. Clear orifice if necessary. Use only orange 10:1 mixing nozzle by: (a) aligning nozzle onto cartridge tip, and (b) twist the gray nut into place. Dispense and discard a small amount of adhesive through nozzle until the adhesive is mixed. 490 ml Cartridge: While holding duo-pak cartridge in an upright position, unscrew the plastic nut and remove and discard the cartridge plug. Place cartridge in a 10:1, 490 ml EPX applicator. Clean orifice if clogged; dispense and discard a small amount of adhesive to even pistons. Attach 10:1 EPX mixing nozzle by: (a) sliding the nozzle onto the cartridge orifice; (b) screwing the plastic nut back onto the cartridge to secure the nozzle. Dispense and discard a small amount of adhesive until the mixed adhesive has a milky white appearance. If adhesive is clear, check the small orifice for debris or flow. Meter-Mix Equipment: Follow manufacturer’s precautions, directions for use, and recommendations. 2) After the adhesive is applied, substrates must be mated within the worklife of the adhesive, 2-2.5 minutes or sooner for one-sided applications. Adhesive thickness less than .005" will yield unpredictable results. The joint design of the substrates should facilitate a .005" to .008" adhesive thickness at the bondline. Adhesive contains .008" micropheres for this purpose. 3) The bonded surfaces should be fixtured, or clamped, for at least 2 hours. The clamping pressure should be sufficient to keep the surfaces in contact during cure (typically 4-8 psi). Plastic parts can be designed to be self-fixturing, negating the need for external fixturing. Note: Heating the bondline to 150-175°F (66-80°C) for 30 minutes will speed up curing. The parts should be dwelled for a minimum of 10 minutes at room temperature prior to heating to allow more adhesive penetration into the substrates before heat-accelerated cure. -7- 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8005 Off-White • DP8005 Black Handling/Curing Information (continued) 4) Cured adhesive appearance: the adhesive will yellow with time; a rippling effect in the adhesive as it cures is normal and indicates that the adhesive is mixed properly and curing normally.

However, all substrates should be clean, dry and free of paint, oxide films, oils, dust, mold release agents and other surface contaminants. The amount of surface preparation directly depends on the bond strength and environmental resistance desired by the user. The following cleaning methods are suggested for common surfaces. Steel and Aluminum 1) Wipe free of dust with oil-free solvent such as acetone or isopropyl alcohol. 2) Sandblast or abrade using clean fine grit abrasives (150 grit or finer). 3) Wipe again with solvent to remove loose particles. 4) If a primer is used, it should be applied within 4 hours after surface preparation (or see instructions pertinent to a specific primer). Note: Aluminum may also be acid etched. Follow the manufacturer’s precautions and directions for this procedure. Plastic/Rubber 1) Wipe with isopropyl alcohol.* 2) Abrade using fine grit abrasives (150 grit or finer). 3) Remove residue by wiping again with isopropyl alcohol.* 4) Allow solvent to evaporate before use. *Note: When using solvents, be sure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use. -8- 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8005 Off-White • DP8005 Black Surface Preparation (continued) Thermoplastic Polyolefin (TPO) 1) Wipe with isopropyl alcohol.* 2) Allow solvent to evaporate before use.
