Henkel 581

Surface Preparation

The 581 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 581 Non-Corrosive Structural Adhesive to the bond area on the non-activated bonding surface.

Join the surfaces as soon as possible and apply 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.

Mixing

Bondmaster 581 should not be mixed with 534 Activator in large quantities, as a vigorous chemical reaction will occur generating a significant amount of heat and vapors.

Clean-Up

Unreacted adhesive can be cleaned up using acetone, isopropanol, or MEK.
