  • Coating compositions
    Patent number: 8399099
    Abstract: The present invention relates to cationically and radically curable coating compositions for coating a surface. The coating compositions consist essentially of a radically or cationically curable monomer, and a metal salt. The metal salt is chosen so that it is reduced at the surface to be coated, and where the standard reduction potential of the metal salt 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 composition is reduced at the surface, thereby initiating cure of the curable component in the compositions. Redox mediated cure of the coating compositions results in a coating or film on the surface. The invention also provides for functionalization of surfaces. Cross-linking of the coating occurs directly on the surface.

    Publication number: 20110297318
    Abstract: A process of bonding a metal substrate to a non-halogenated polymer, especially of bonding a polyolefin overcoat to a metallic tube or pipe, using an epoxy-based adhesive which comprises at least one salt of a metal ion M in an oxidation state of n which has a standard reduction potential E0M more positive than the standard reduction potential of the surface of the metal substrate; an object comprising a metal substrate and a non-halogenated polymer bonded together by this process; a tube or pipe made of a metal substrate onto which a layer of a non-halogenated polymer is bonded by a cured epoxy-based adhesive.

  • Surface-promoted cure of cationically curable compositions comprising vinyl ethers
    Patent number: 8071698
    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.
