Overlap Shear (ASTM D1002) Overlap Shear (ASTM D-1002-64, 3M Test Method C-236) strength was measured on 1" wide x 1/2" overlap specimen. These bonds were made individually using 1" x 4" pieces of substrates except for Aluminum. Two panels 0.063 in. thick, 4 in. x 7y in of 2024T-3 clad aluminum were bonded and cut into 1 in. wide samples after 24 hours. The thickness of the adhesive bond line was approximately 0.005". All strengths were measured at 23°C (73°F) except when noted. 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, 0.125in.; plastics, 0.125 in. and samples were allowed to cure at 24°C (75°F) and approximately 50% RH for 1 week before tested. The separation rate of the testing jaws was 0.1 inch per minute for metals and 2 inches per minute for plastics. B. Floating Roller Peel (Bell Peel) (ASTM D3167) Bell peel strengths were measured on 1 in. wide bonds at the temperatures noted. The testing jaw separation rate was 6 in. per minute. The bonds were made with 0.064 in. bonded to 0.025 in. thick adherends. C. Cure Cycle All bonds were cured 7 days at 23°C (73°F) at 50% RH before testing or subjected to further conditioning or environmental aging. -4 ™ Scotch-Weld™ Urethane Adhesive DP604NS, Black Handling and Application Information Directions for Use 3M™ Scotch-Weld™ Urethane Adhesive DP604NS is supplied in dual syringe plastic duo- pak cartridges as part of the 3M™ EPX Applicator System. The duopak cartridges are supplied in 50 ml and 400 ml configurations. To use the EPX cartridge system simply insert the duo-pak cartridge into the EPX applicator. 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 typical uncured properties section of this data sheet. Complete 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 uses because of their variable shot size and flow rate characteristics and are adaptable to most applications. Apply adhesive to clean, dry surfaces, joint parts and secure until adhesive sets. Surface Preparation The following surface preparations were used for substrates described in this Technical Data Sheet. A. Aluminum Etch Optimized FPL Etch - 3M (test method C-2803) 1. Alkaline degrease – Oakite 164 solution (9-11 oz./gallon water) at 88°C ± 5°C (190°F ± 10°F) for 10-20 minutes. Rinse immediately in large quantities of cold running water (3M test method C-2802). 2. Optimized FPL Etch Solution (1 litre): Material Amount Distilled Water 700 ml plus balance of litre (see below) Sodium Dichromate 28 to 67.3 grams Sulfuric Acid 287.9 to 310.0 grams Aluminum Chips 1.5 grams/liter of mixed solution To prepare 1 litre of this solution, dissolve sodium dichromate in 700 ml of distilled water. Add sulfuric acid and mix well. Add additional distilled water to fill to 1 litre. Heat mixed solution to 66 to 71°C (150 to 160°F). Dissolve1.5 grams of 2024 bare aluminum chips per litre of mixed solution. Gentle agitation will help aluminum dissolve in about 24 hours. To FPL etch panels, place them in the above solution at 66 to 71°C (150 to 160°F) for 12 to 15 minutes. Note: Review and follow precautionary information provided by chemical suppliers prior to preparation of this etch solution. Rinse immediately in large quantities of clear running tap water. -5 ™ Scotch-Weld™ Urethane Adhesive DP604NS, Black Surface Preparation (Continued) Dry – air dry approximately 15 minutes followed by force dry at 60°C (140°F) maximum for 10 minutes (minimum). 3. Both surface structure and chemistry play a significant role in determining the strength and permanence of bonded structures. It is therefore advisable to bond or prime freshly primed clean surfaces as soon as possible after surface preparation in order to avoid contamination and/or mechanical damage. Please contact your 3M sales representative for primer recommendations. B. Oakite Degrease Oakite 164 solutions (9-11 oz./gallon of water) at 88°C ± 5°C (190°F ± 10°F) for 2 minutes. Rinse immediately in large quantities of cold running water. C. MEK/Abrade/MEK Wipe surface with a methyl ethyl ketone (MEK) soaked swab, abrade and wipe with a MEK soaked swab.* Allow solvent to evaporate before applying adhesive. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use. D. Isopropyl Alcohol Wipe Only Surface Preparation Wipe surface with an isopropyl alcohol soaked swab.* Allow solvent to evaporate before applying adhesive. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use. E. Isopropyl Alcohol/Abrade/Isopropyl Alcohol Surface Preparation Wipe surface with an isopropyl alcohol soaked swab, abrade using clean fine grit abrasives, and wipe with an isopropyl alcohol soaked swab.* Then allow solvent to evaporate before applying adhesive. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use. -6 ™ Scotch-Weld™ Urethane Adhesive DP604NS, Black Storage Store products at 15-27°C (60-80°F) for maximum shelf life.
