Henkel Bondmaster 4L67

Surface Preparation

BONDMASTER 4L67 bonds well to many untreated surfaces. However, adhesion is often improved by surface preparation before bonding. The surface should be free of contamination such as dirt, dust, grease or oil. An alcohol wipe is suitable for cleaning most surfaces. Optimum strength is obtained by abrading the surface followed by a solvent wipe to remove any loose particles. Polyolefins should be corona treated, plasma or flame treated before bonding.

Application

BONDMASTER 4L67 is best applied by extruding the product onto the substrate to be sealed or bonded. Sufficient product must be applied to seal all gaps, and completely coat the part to be bonded or sealed. After dispensing onto the part, the product should be cured as soon as possible to prevent any prereaction with ambient light.

BONDMASTER 4L67 may be applied via a pressure pot, or piston pump dispensing system. All fittings and tubing used in the dispensing system must be opaque to light. If the product is transferred from a large container to a smaller hand held dispensing bottle, that bottle must be light impenetrable.

Clean-Up

Unreacted material can be cleaned up using acetone
