Henkel Technomelt PA 646 Black High Performance Hot Melt

Henkel Technomelt PA 646 Black High-Performance Hot Melt Overview

Henkel Technomelt PA 646 Black high-performance thermoplastic polyamide is designed to meet low-pressure molding process requirements. This product can be processed at low processing pressure due to its low viscosity, allowing the encapsulation of fragile components without damage. This material produces no toxic fumes in the process and provides a good balance of low and high-temperature performance.

Features and Benefits
