  • Best Practices for 3M Scotch-Weld Urethane Adhesive DP605NS Off-White

    *See Terms of Use Below

    1. Surface Preparation

      To prepare 1 liter 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 liter. Heat mixed solution to 66 to 71°C (150 to 160°F).

      Dissolve1.5 grams of 2024 bare aluminum chips per liter of mixed solution. Gentleagitation will help aluminum dissolve in about 24 hours.

      To FPL etch panels, place them in the above solution at 150 to 160°F (66 to 71°C) 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.

      Dry – air dry approximately 15 minutes followed by force dry at 140°F (60°C) maximum for 10 minutes (minimum).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.

      Oakite Degrease: Oakite 164 solutions (9-11 oz./gallon of water) at 190°F ± 10°F (88°C ± 5°C) for 2 minutes. Rinse immediately in large quantities of cold running water.

      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.

      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.

      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.

    2. Application

      3M™ Scotch-Weld™ Urethane Adhesive DP605NS is supplied in dual syringe plastic duo- pak cartridges as part of the 3M™ EPX™ Applicator System. The duo-pak cartridges are supplied in 50 ml and 200 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.

      Apply adhesive to clean, dry surfaces, joint parts and secure until adhesive sets.

    3. Mixing

      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.

    4. Clean-Up

      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.
