The mechanism of cure initiation of a surface-activated adhesive
Source abstract
Abstract
The mechanism of cure initiation of a recently developed surface-activated adhesive is described. This one-part acrylic adhesive is catalyzed to cure by interaction with a zinc substrate. The critical ingredients for surface initiation are a sulfonyl halide, a copper salt, and an acid. The first step is reduction of the sulfonyl halide to a zinc sulfinate salt on the metal surface. The sulfinate then becomes protonated through action of the acid and is released from the surface. The sulfinic acid interacts with copper ion, perhaps through an intermediate sulfinyl sulfone moiety, and subsequently initiates polymerization of the methacrylate monomers.
