Handling/Curing Information Directions For Use 1. For high strength structural bonds, paints, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed. However, the amount of surface preparation necessary directly depends on the required bond strength and the environmental aging resistance desired by the user. For suggested surface preparations on common substrates, see the section on surface preparation. 2. Mixing For Duo Pak Cartridges 3M™ Scotch-Weld™ Epoxy Adhesives DP190 Translucent and DP190 Gray are supplied in a dual syringe plastic duo-pak cartridge as part of the 3M™ EPX Applicator system. To use, simply insert the duo-pak cartridge into the EPX applicator and start the plunger into the cylinders using light pressure on the trigger. Next, remove the duo-pak cartridge cap and expel a small amount of adhesive to be sure both sides of the duo-pak cartridge are flowing evenly and freely. If automatic mixing of Part A and Part B is desired, attach the EPX applicator mixing nozzle to the duo-pak cartridge and begin dispensing the adhesive. For hand mixing, expel the desired amount of adhesive and mix thoroughly. Mix approximately 15 seconds after uniform color is obtained. For Bulk Containers Mix thoroughly by weight or volume in the proportions specified in the typical uncured properties section. Mix approximately 15 seconds after uniform color is obtained. 3. For maximum bond strength, apply adhesive evenly to both surfaces to be joined. 4. Application to the substrates should be made within 75 minutes. Larger quantities and/or higher temperatures will reduce this working time. 5. Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until completely firm. Heat up to 200°F (93°C) will speed curing. These products will cure in 7 to 14 days @ 75°F (24°C). 6. Keep parts from moving during cure. Contact pressure necessary. Maximum shear strength is obtained with a 3-5 mil bond line. 7. Excess uncured adhesive can be cleaned up with ketone type solvents.* *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use. Adhesive Coverage (typical): A 0.005 in. thick bondline will yield a coverage of -5- 3M™ Scotch-Weld™ Epoxy Adhesives DP190 Translucent and Gray Surface Preparation For high strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed. However, the amount of surface preparation necessary directly depends on the required bond strength and the environmental aging resistance desired by the user. The following cleaning methods are suggested for common surfaces: Steel: 1. Wipe free of dust with oil-free solvent such as acetone, isopropyl or alcohol solvents.* 2. Sandblast or abrade using clean fine grit abrasives. 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. Aluminum: 1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F (87°C) ± 10°F for 10-20 minutes. Rinse immediately in large quantities of cold running water.* 2. Acid Etch: Place panels in the following solution for 10 minutes at 150°F (65°C) ± 5°F.* Sodium Dichromate 4.1 - 4.9 oz./gallon Sulfuric Acid, 66°Be 38.5 - 41.5 oz./gallon 2024-T3 aluminum (dissolved) 0.2 oz./gallon minimum Tap water as needed to balance 3. Rinse: Rinse panels in clear running tap water. 4. Dry: Air dry 15 minutes; force dry 10 minutes at 150°F (65°C) ± 10°F. 5. If primer is to be used, it should be applied within 4 hours after surface preparation. Plastics/Rubber: 1. Wipe with isopropyl alcohol.* 2. Abrade using fine grit abrasives. 3. Wipe with isopropyl alcohol.* Glass: 1. Solvent wipe surface using acetone or MEK.* 2. Apply a thin coating (0.0001 in. or less) of 3M™ Scotch-Weld™ Metal Primer EC3901 or equivalent to the glass surfaces to be bonded and allow the primer to dry before bonding. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use. Application Equipment Suggestions For smaller or intermittent applications, the 3M™ EPX Applicator is a convenient method of application. For larger applications these products may be applied by use of flow equipment. Two-part meter/mixing/proportioning/dispensing equipment is available for intermittent or production line use. These systems may be desirable because of their variable shot size and flow rate characteristics and are adaptable to many applications. -6- 3M™ Scotch-Weld™ Epoxy Adhesives DP190 Translucent and Gray Storage Store products at 60-80°F (15-27°C) for maximum shelf life.
