Curing Agent WS 5

Description

CURING AGENT WS 5 is a cross-linking agent (water dispersion of modified ethylenurea), developed to improve the cohesion of water-borne adhesives.

Application

When CURING AGENT WS 5 is added to aqueous binders (acrylic or SBR latex), a heat treatment after drying consistently improves cohesion and moisture resistance of the film.
Where added to textile finishing agents, it will remarkably improve the resistance to washing and abrasion.
