  • Best Practices for Bostik 70-03A SKF

    *See Terms of Use Below

    1. Application

      Bostik 70-03A-SKF can easily be extruded with a handgun or air-pressure gun at temperatures between 45°F to 100°F (5°C to 35°C).

      Bostik 70-03A-SKF can easily be extruded with a handgun or air-pressure gun at temperatures between 45°F to 100°F (5°C to 35°C).

      In bonding applications, the substrates have to be assembled within 25 minutes (at 20°C/50% R.H.) after applying 70-03A-SKF. In general, an adhesive thickness of 0.062-in. or 1/16-in. (2 mm) is recommended.

    2. Clean-Up

      Cleaning tools or removing uncured residue of Bostik® 70-03A-SKF can be done with a clean white/colorless cloth, moistened with IPA (Isopropyl alcohol). Check substrate compatibility with IPA (Isopropyl alcohol) before proceeding.
