BETASEAL® 1766 EU

BETASEAL® 1766 EU is a high viscosity, high modulus, glass bonding adhesive that can be used primerless to paint and glass. Due to its chemistry, it delivers a high initial handling strength to hold the position of the bonded parts. It is a one component, ambient moisture curing, solvent free adhesive for direct glazing applications. It shows excellent sag and bead stability. Skin formation and curing are dependent on humidity, temperature and application dimension.
