POLYURETHANE ADHESIVE COMPOSITIONS HAVING HIGH FILLER LEVELS

摘要

In one aspect, this invention is a composition comprising a urethane prepolymer having isocyanate moieties; a catalytic amount of a compound which catalyzes the reaction of isocyanate moieties with water or an active hydrogen containing compound; and untreated calcium carbonate as filler. The composition of the invention can be used to bond a window into a structure especially for the automobile windshield installation with good adhesion strength and durability.
