For high strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed from substrates to be bonded. However, the amount of surface preparation necessary directly depends on the user's required bond strength, environmental aging resistance and economic practicalities. For specific surface preparations on common substrates, see the section on surface preparation. 2. These products consist of two parts. Mixing For Duo-Pak Cartridges 3MTM Scotch-WeldTM Epoxy Adhesive DP110 Translucent and Gray are supplied in a dual syringe plastic duo-pak cartridge as part of the 3MTM EPXTM 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 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 a uniform color is obtained. For Bulk Containers Mix thoroughly by weight or volume in the proportions specified on the product label or in the uncured properties section. Mix approximately 15 seconds after a uniform color is obtained. 3. For maximum bond strength apply product evenly to both surfaces to be joined. 4. Application to the substrates should be made within 8 minutes. Larger quantities and/or higher temperatures will reduce this working time. 5. Join the adhesive coated surfaces and allow to cure at 60F (16C) or above until completely firm. Heat up to 200F (93C), will speed curing. These products will fully cure in 48 hours @ 75F (24C). 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 the manufacturer's precautions and directions for use. Adhesive Coverage: A 0.005 in. thick bondline will typically yield a coverage of 320 sq. ft./gallon. -5- 3MTM Scotch-WeldTM Epoxy Adhesives DP110 Translucent and Gray Application Equipment Suggestions These products may be applied by spatula, trowel or flow equipment. Surface Preparation For high strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed from substrate to be bonded. However, the amount of surface preparation necessary directly depends on the user's required bond strength, environmental aging resistance and economic practicalities. The following cleaning methods are suggested for common surfaces: Two part mixing/proportioning/dispensing equipment is available for intermittent or production line use. These systems are ideal because of their variable shot size and flow rate characteristics and are adaptable to many applications. Steel: 1. Wipe free of dust with oil-free solvent such as acetone or isopropyl 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 190F 10F (88C 23C) 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 150F 5F (66C 23C). Sodium Dichromate 4.1 - 4.9 oz./gallon Sulfuric Acid, 66Be 38.5 o 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 150F 10F (66C 23C). 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.* *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer's precautions and directions for use. -6- 3MTM Scotch-WeldTM Epoxy Adhesives DP110 Translucent and Gray Storage Store products at 60-80F (16-27C) for maximum storage life.
