Abstract
Provided are two part hybrid adhesives that comprise an organoborane amine complex, a polyamine, a component polymerizable by free radical polymerization, and a polyisocyanate component. An isocyanate terminated prepolymer can advantageously be used in the practice of the invention. The adhesive is particularly well suited for low surface energy plastic bonding.
