Data were collected using a Sintech 5GL Mechanical Tester with a 2000# or 5000# load cell. Test rate was 0.1"/minute. Strength determined at 75F (24C) unless otherwise noted. 3) Peel tests (ASTM D1876-61T) on FPL etched, 0.032" gauge aluminum, with a .017" bondline thickness. Jaw separation rate 20"/min. All bonds were allowed to cure for at least 6 hours at 75F (24C) before testing. 4) Environmental tests were conducted by immersing bonded coupons prepared in accordance to description in footnote 2. -4- 3MTM Scotch-WeldTM Low-Odor Acrylic Adhesives DP810 * DP810 Black * DP810 NS Handling/Curing Information Directions for use: Apply adhesive to clean, dry substrates, which are free of paint, oxide films, oils, dust, mold release agents and all other surface contaminants. See the Surface Preparation section for specific substrate preparation method. 50 ml cartridge:. Place Duo-Pak cartridge in 3MTM EPXTM Applicator. Remove cap. Dispense and discard a small amount of adhesive to assure even ratio and free flow. Clear orifice if necessary. Attach mixing nozzle. Apply adhesive to clean surfaces, join parts, secure until adhesive sets. 200/400 ml cartridge While holding Duo-Pak cartridge in an upright position, remove and discard the insert from the cartridge by unscrewing plastic nut and removing metal washer. Place cartridge in a 1:1 200/400 ml EPX applicator. Dispense and discard a small amount of adhesive to ensure even ratio and free flow. Attach mixing and nozzle and secure with plastic retaining nut. Apply adhesive to clean surfaces, join parts, secure until adhesive sets. Clean-up: Excess adhesive can be removed with solvent such as MEK.* Edge tack on a finished part or bond line can be removed with isopropyl alcohol.* *Note: When using solvents, extinguish all ignition sources and follow the manufacturer's precautions and directions for use. Heat Cure: Full cure can be attained by raising the bondline temperature to 120F (49C) for 30 minutes or to 150F (66C) for 10 minutes. -5- 3MTM Scotch-WeldTM Low-Odor Acrylic Adhesives DP810 * DP810 Black * DP810 NS Surface Preparation 3MTM Scotch-WeldTM Low-Odor Acrylic Adhesives can bond oily metal, plastic and other substrates with very little surface preparation. However, for the most consistent results and environmental resistance, all substrates should be clean, dry and free of paint, oxide films, dust, mold release agents and all 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 (180 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 (180 grit or finer). 3) Remove residue by wiping again with isopropyl alcohol.* *Note: When using solvents, extinguish all ignition sources and follow the manufacturer's precautions and directions for use. -6- 3MTM Scotch-WeldTM Low-Odor Acrylic Adhesives DP810 * DP810 Black * DP810 NS Storage For maximum shelf life, store Duo-Pak cartridges and bulk containers at 32F (0C) to 40F (4C). Do not freeze. Shelf Life When stored at the recommended temperatures in the original unopened containers, this product has a shelf life of twelve months from date of shipment from 3M.
