Henkel Technomelt PUR 4663 Hot Melt Overview

Technomelt PUR 4663 is a light-ivory-colored, multi-purpose reactive hotmelt that is used in panel bonding. It undergoes an additional crosslinking reaction after cooling. It shows high initial strength in combination with relatively long open time - assembly is possible after cooling of the adhesive. After curing the product has duroplastic properties and very high heat and cold resistance. Suitable for flat lamination and assembly application in industrial production.
