3 / 4 page  3 Date : March 1996 EPX Epoxy Adhesive DP460 Storage Conditions Store product at 16 to 27°C for maximum storage life. High temperatures reduce normal storage life. Rotate stock on a "first in- first out" basis. Directions for Use /Clean Up Place the cartridge into the 3M EPX Applicator and clip into position. Remove the resealable cap. Expel a small quantity of adhesive and ensure both components flow freely. Attach correct mixer nozzle (this should have 20 or more elements). Dispense the adhesive as required. When finished either leave the nozzle in place and store, or remove the nozzle, wipe clean the tip, and replace cap. To re-start after storage remove the old nozzle with cured adhesive and re-fit a new nozzle, or remove the cap and fit a new nozzle. Surface Preparation: The degree of surface preparation depends on the bond strength required and the environment likely to be encountered by the bonded structure. For most plastics solvent wiping with 3M VHB surface cleaner, followed by abrasion with 3M Scotchbrite 7447, followed by a further solvent wipe until clean, will give good performance (except for acetal, polyethylene and polypropylene and some other low surface energy materials). This also applies to powder coat paints and other stoved paint systems. The same surface preparation will also give good adhesion to metal surfaces. The objective is to remove loosely attached surface films such as oils, waxes, dusts, mill-scale, loose paints and all other surface contaminants in addition to enhancing mechanical adhesion. Grit- blasting using a clean, fine grit also offers excellent adhesion on many metallic substrates. Where humid environments are likely to be encountered by metallic substrates we recommend additional priming with 3M Scotch- Weld 3901. Alternatively, chemical conversion coating techniques combined with priming can offer the best durability. Clean-Up: Excess uncured adhesive can be removed with the following solvents: 3M VHB Surface Cleaner (mild alcohol based cleaner) 3M Scotch-Grip Solvent No2. (Ketone blend) 3M Industrial Cleaner (Aerosol). |
