  • Best Practices for 3M AC78

    *See Terms of Use Below

    1. Surface Preparation

      Prepare bonding surfaces according to Surface Preparation recommendations for the cyanoacrylate that will be used.

    2. Application

      Apply primer to all difficult-to-bond plastic surfaces

      Allow solvent to dry completely.

      Promptly bond with a Scotch-Weld™ cyanoacrylate for plastic or elastomeric bonding.

    3. Testing

      These products should be tested on substrates before use since their overspray or excess may attack certain substrates (especially some plastics) causing unsightly effects.
