Henkel Technomelt PA 6900 Highly Flexible Polyamide Hot Melt Adhesive

Technomelt PA 6900 for High-Strength General Assembly Applications

Henkel Technomelt PA 6900 is a colorless polyamide hot melt designed for demanding general assembly applications. It offers excellent flexibility with 600% elongation and strong mechanical performance for bonded components. This grade is well suited for bonding glass, metals, and ceramics where durability and movement resistance are required. Best results are achieved when substrates are preheated to promote optimal wetting and adhesion.
