ADHESIVE COMPOSITION WITH ENHANCED CURE THROUGH VOLUME

摘要

Curing through large bond gaps, of approximately 0.5 - 1.0 mm, has proven particularly challenging in the field of adhesives technology. Most noteworthy is the difficulty associated with providing one-part adhesive formulations capable of curing through large bond gaps. Disclosed herein are radically curable compositions comprising a radically curable component, and an initiator component capable of initiating cure of the radically curable component. The initiator comprises at least one metal salt and a free radical generating component. The metal salt of the composition is chosen so that it is reduced at the surface to which it is applied. The compositions further comprise an additive, as disclosed herein, for improving the ability of the composition to cure through large bond gaps.
