ACCELERATE CURE OF MOISTURE CURABLE POLYURETHANE ADHESIVE COMPOSITIONS USEFUL FOR BONDING GLASS

摘要

The adhesive system of the invention is especially useful in bonding replacement windows into vehicles. They allow for sufficient working time while still realizing a fast drive away time. The adhesive system is comprised of a moisture curable adhesive and a cure accelerator that may be applied using a simple single caulk gun and may be applied at ambient temperatures such as -10°C and about 45°C. The cure accelerator is comprised of a polyol having a backbone that has at least one amine in the backbone. The moisture curable adhesive typically is comprised of an isocyanate terminated prepolymer.
