Patent ID: 8071698

Claim:
A cationically curable composition comprising: a. a cationically curable component; b. an accelerator species comprising at least one vinyl ether functional group; and c. an initiator component having a standard reduction potential, said initiator component comprising at least one metal salt wherein said metal salt is soluble in the cationically curable component and accelerator species; wherein the standard reduction potential of the initiator component is greater than the standard reduction potential of a substrate on which the cationically curable composition is to be applied, wherein when the composition is placed in contact with a surface of a substrate, the metal salt of the initiator component of the composition is reduced at the surface of the substrate, thereby initiating cure of the cationically curable component of the composition; and wherein the substrate is constructed from one of iron, steel, mild steel, gritblasted mild steel, aluminium, aluminium oxide, copper, zinc, zinc oxide, zinc bichromate, and stainless steel.
