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.
L'invention porte sur des adhésifs hybrides en deux parties qui comprennent un complexe organoborane-amine, une polyamine, un composant polymérisable au moyen dune polymérisation par radicaux libres et un composant de polyisocyanate. Un prépolymère à terminaison isocyanate peut être avantageusement utilisé dans la pratique de l'invention. L'adhésif est particulièrement bien approprié pour un collage de matières plastiques à faible énergie de surface.
