A method for bonding a material to a first substrate surface that includes providing a catalyst at the first substrate surface and then contacting that surface with a material that undergoes a metathesis reaction to bond the material to the first substrate surface. There are two embodiments of this method&#x2014;a coating process and an adhesive process. In the coating embodiment, the metathesizable material is contacted with the catalyst on the substrate surface so that it undergoes metathesis polymerization to form the coating. The adhesive process includes (a) providing a catalyst at the first substrate surface, (b) providing a metathesizable material between the first substrate surface and the second substrate surface, and (c) contacting the catalyst on the first substrate surface with the metathesizable material so that the metathesizable material undergoes a metathesis reaction and bonds the first substrate surface to the second substrate surface.

Contact metathesis polymerization

An adhesive or coating composition prepared by mixing together at least one metathesizable highly-reactive cycloolefin (e.g., a norbornadiene) and a metathesis catalyst. The use of highly-reactive cycloolefins can provide exceptional adherence to a low-surface-tension substrate. Another embodiment is a two-part adhesive or coating system wherein the first part includes at least one first metathesizable material, and the second part includes at least one liquid metathesis oligomer or polymer and a metathesis catalyst.

Metathesis polymerization adhesives and coatings

Emissive coatings for flexible substrates, preferably elastomers or elastomers bonded to metal are disclosed The coating composition is formed by combining parts (a) and (b) where part (a) comprises an organic solution or aqueous dispersion of a functional group containing polymer or copolymer and thermal conductive filler; and part (b) comprises a liquid curing component, for example a poly isocyanate, a carbodiimide, or an amino resin. The coating compounds can be applied to an substrate either before or after the substrate has been vulcanized. The coatings can be cured at ambient temperatures and provide heat dissipation over long term service at elevated temperatures.
