  • Best Practices for Henkel 531

    *See Terms of Use Below

    1. Surface Preparation

      The 531 adhesive requires no surface preparation on most metal, ferrite, and glass surfaces. For optimum bond strength on metal parts, the surface should be washed with a solvent or cleansing solution, abraded with an abrasive pad, and then rinsed with a solvent or cleansing solution. Glass surfaces should be cleaned with a commercial glass cleaner before bonding. Painted surfaces should be abraded lightly and then wiped clean.

    2. Application

      Apply BONDMASTER 534 Activator by spraying, wiping, or brushing a thin film of the activator on one of the bonding surfaces.

      Apply BONDMASTER 531 Adhesive to the bond area on the non-activated bonding surface.

      Join surfaces with sufficient pressure to maintain intimate contact between the parts until handling strength is obtained.

      A 15 - 30 second clamp time is usually required for bonding of parts with minimal gap.

    3. Clean-Up

      Unreacted Part A & Part B can be cleaned up using acetone, isopropanol, or MEK.
