For optimum 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 directly depends on the required bond strength and the environmental aging resistance desired by user. For specific surface preparations on common substrates, see the following section on Surface Preparation. 2. Use gloves to minimize skin contact with adhesive. 3. These products consist of two parts. Mixing and Applying For Duo-Pak Cartridges - 50 ml 3MTM Scotch-WeldTM DP-100 and DP-100 NS Adhesives are suppled in a dual syringe plastic Duo-Pak cartridge as part of the 3MTM Scotch-WeldTM 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 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 uniform color is obtained. For Duo-Pak Cartridges - 200/400 ml Directions for Use: While holding cartridge in an upright position, remove insert from Duo-Pak cartridge by unscrewing plastic nut. Detach metal removal disc from insert to free plastic nut for nozzle attachment. Clear orifices if necessary. Attach mixing nozzle and secure with plastic nut. Place cartridge into EPX Applicator. Dispense a small quantity of adhesive to assure both components are dispensing equally. Apply adhesive to clean surfaces, join parts, secure until set up (20 minutes @ 75F [24C]). Leave nozzle attached to store. Replace nozzle after storage. 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. 4. For maximum bond strength apply adhesive evenly to both surfaces to be joined. 5. Application to the substrates should be make within 5 minutes. Larger quantities and/or higher temperatures will reduce this working time. 6. 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 24-48 hours @ 75F (24C). 7. Keep parts from moving during cure. Contact pressure is necessary. Maximum shear strength is obtained with a 3-5 mil bond line. 8. Excess uncured adhesive can be cleaned up with ketone type solvents.* *Note: When using solvents, extinguish all ignition sources 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. -3- 3MTM Scotch-WeldTM Epoxy Adhesives DP-100 Clear * DP-100 NS Translucent Surface Preparation For optimum 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 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 or isopropyl alcohol.* 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. Vapor Degrease: Perchlorethylene condensing vapors for 5-10 minutes. 2. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190F 10F (88C 5C) for 10-20 minutes. Rinse immediately in large quantities of cold running water. 3. Acid Etch: Place panels in the following solution for 10 minutes at 150F 5F (66C 2C). Sodium Dichromate 4.1 - 4.9 oz./gallon Sulfuric Acid, 66Be 38.5 - 41.5 oz./gallon 2024-T3 aluminum (dissolved) 0.2 oz./gallon minimum Tap Water as needed to balance 4. Rinse: Rinse panels in clear running tap water. 5. Dry: Air dry 15 minutes and force dry 10 minutes at 150F 10F (66C 5C). 6. 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 and follow the manufacturer's precautions and directions for use. Application Equipment Suggestions For small or intermittent applications the 3MTM Scotch-WeldTM EPXTM applicator is a convenient method of application. For larger applications these adhesives may be applied by use of flow equipment. Two-part meter/mixing/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. -4- 3MTM Scotch-WeldTM Epoxy Adhesives DP-100 Clear * DP-100 NS Translucent Typical Adhesive Performance Characteristics Note: The following product performance data was obtained in the 3M laboratory under the conditions specified. The following data shows typical results obtained with 3MTM Scotch-WeldTM Epoxy Adhesives DP-100 and DP-100 NS when applied to properly prepared substrates, cured for 7 days at 73F (23C) under 2 psi cure pressure, and tested according to the test methods indicated. The following technical information and data should be considered representative or typical only and should not be used for specification purposes. A. Overlap Shear Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap specimens. These bonds were made individually using 1 in. x 4 in. pieces of substrate except for aluminum. Two panels 0.063 in. thick, 4 in. x 7 in. of 2024 T-3 clad aluminum were bonded and cut into 1 in. wide samples after 24 hours. The thickness of the bond line was 0.005 - 0.008 in. All strengths were measured at 73F (23C) except where noted. (Tests per ASTM D 1002-72.) The separation rate of the testing jaws was 0.1 in. per minute for metals, 2 in. per minute for plastics and 20 in. per minute for rubbers. The thickness of the substrates were: steel, 0.060 in., other metals, 0.05-0.064 in.; rubbers, 0.125 in.; plastics, 0.125 in. B. T-peel T-peel strengths were measured on 1 in. wide bonds at 73F (23C). The testing jaw separation rate was 20 inches per minute. The substrates were 0.032 in. thick. (Tests per ASTM D 1876-61T.) C. Cure Cycle With the exception of Rate of Strength Build-Up Tests, all bonds were cured 7 days at 73F (23C)/50% RH before testing or subjected to further conditioning or environmental aging.
