Directions for Use 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 depends on the required bond strength and the environmental aging resistance desired by user. For specific surface preparations on some common substrates, see the section on surface preparation. 3MTM Scotch-WeldTM Epoxy Adhesive DP100 FR is 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 simultaneous mixing of Part A and Part B is desired, attach the EPX mixing nozzle to the duo-pak cartridge and begin dispensing the adhesive. When mixing Part A and Part B manually, the components must be mixed in the ratio indicated in the Physical Uncured Properties section. Thorough mixing of the two components is required to obtain optimum properties. Two-part mixing/proportioning/dispensing equipment is available for intermittent or production line use. These systems are ideal for line use because of their variable shot size and flow rate characteristics and are adaptable to most applications. -2- 3MTM Scotch-WeldTM Epoxy Adhesive DP100 FR Handling/Application Information (continued) 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 depends on the required bond strength and the environmental aging resistance desired by user. The following cleaning methods are suggested for these 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. *When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer's precautions and directions for use. Aluminum: 1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190F (88C) 10F (-13C) 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 (66C) 5F (-15C). Sodium Dichromate Sulfuric Acid, 66Be 2024-T3 aluminum (dissolved) Tap Water as needed to balance 4.1-4.9 oz./gallon 38.5-41.5 oz./gallon 0.2 oz./gallon minimum Note: Read and follow component suppliers environmental, health and safety recommendations prior to preparing this etch solution. 3. Rinse: Rinse panels in clean running tap water. 4. Dry: Air dry 15 minutes; force dry 10 minutes at 190F (88C) 10F (5C). Plastics/Rubber 1. Wipe with isopropyl alcohol.* 2. Abrade using fine grit abrasives. 3. Wipe with isopropyl alcohol.* *When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer's precautions and directions for use. -3- 3MTM Scotch-WeldTM Epoxy Adhesive DP100 FR Handling/Application Information (continued) Surface Preparation (continued) Glass 1. Solvent wipe surface using acetone or methyl ethyl ketone (MEK).* 2. Apply a thin coating (0.0001 in. or less) of primer such as 3MTM Scotch-WeldTM Structural Adhesive Primer EC-3901 to the glass surfaces to be bonded and allow the primer to dry before bonding. *When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer's precautions and directions for use. Typical Adhesive Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. The following product performance data were obtained in the 3M laboratory under the conditions specified. The following data show typical results obtained with the 3MTM Scotch-WeldTM Epoxy Adhesive DP100 FR when applied to properly prepared substrates, cured, and tested according to the specifications indicated. This data was generated using the 3MTM EPXTM Applicator System equipped with an EPX static mixer, according to manufacturer's directions. Thorough manual mixing should afford comparable results.
