Abstract:
A method for bonding a material to a fibrous substrate surface that includes providing a catalyst at the fibrous substrate surface, then contacting that surface with a material that undergoes a metathesis reaction and then bonding the fibrous substrate surface to a second substrate. There are two embodiments of this method - 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 fibrous substrate surface, (b) contacting the catalyst on the fibrous substrate surface with a metathesizable material so that the metathesizable material undergoes a metathesis reaction; and (c) contacting the fibrous substrate surface with a second substrate surface.
Abstract:
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.

Abstract:
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.

Abstract:
The present invention provides an ambient temperature cured coated articles where the coating is rubbery, high elongation, weatherable coating compositi on as a mixture of two parts, one part containing a solution of a functional fi lm forming polymer, and the other part providing the curing component. The stability as a premixed, one-part solution is limited to up to several month s. The curable film former and curing component are mixed together at an overal l 4% to 25% solids content. The viscosity is less than 20,000 cps (Brookfield) such that the coating can be sprayed, brushed or dipped to form thin coating s of from 0.001 - 0.020 mils. Coated rubber articles containing metal conducti ve particles exhibit heat emissive properties useful for extending the service life of the articles.
