Product Highlights

Henkel Technomelt PUR 4511B Hot Melt Overview

Technomelt PUR 4511B is a 100% solids, moisture-curing hot melt adhesive designed for excellent adhesion to challenging surfaces like polycarbonate and treated polypropylene.

Ideal for bonding headlamp assemblies, it withstands stringent performance requirements. Its robust and consistent performance reduces failure risks, offering a faster cure speed and typically bubble-free material that minimizes bond failure.
