  • Best Practices for 3M Scotch-Weld Instant Adhesive Accelerator AC452

    *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

      Adhesive is applied to one substrate and activator is sprayed or painted on to the other.

      Apply activator by wipe, brush, or pump spray.

      Allow activator's solvent to evaporate completely.

      Apply cyanoacrylate adhesive within one minute of solvent drying.

      Reapply activator if there is a delay greater than one minute between activator drying and cyanoacrylate dispensing.

    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.
