ABSTRACT:
The present invention relates to cationically curable compositions for curing on a surface comprising a cationically curable component, an accelerator species comprising at least one vinyl ether functional group and an initiator component capable of initiating cure of the cationically curable component. The initiator comprises at least one metal salt, which is chosen so that it is reduced at the surface, and where the standard reduction potential of the initiator component is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt of the initiator component of the composition is reduced at the surface, thereby initiating cure of the cationically curable component of the composition. The accelerator species comprising at least one vinyl ether functional group greatly enhances the rate of cure. No catalytic component is required in the composition for efficient cure.
