Light and moisture curable compositions

Abstract

Curable compositions comprising a urethane multifunctional (meth)acrylate, a photo initiator system, a moisture-cure initiator, and an oligomer, where the oligomer is represented by the formula (I) where each X1 is independently alkylene; each X2 is independently alkylene, polyether, polyester, or polyurethane; R1 is a (meth)acrylate; R2 is urethane or isocyanate; and R3 alkylene (meth)acrylate, polyester (meth)acrylate, polyether, polyester, polyurethane, or nothing, and where the ratio of (meth)acrylate to isocyanate in the oligomer is 1:1 to 1:2. Methods of making curable compositions, methods of sealing a substrate, and methods of adhering two substrates are provided.
