Best Practices for Henkel 531
-
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.
-
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.
-
Clean-Up
Unreacted Part A & Part B can be cleaned up using acetone, isopropanol, or MEK.
