Abstract:
A primer composition that provides a primer layer that improves adhesion between a coating and a substrate. The primer composition includes an adhesion promoter and a catalyst. The adhesion promoter includes a functional group that reacts with the substrate and a functional group that reacts with the coating or a component of the coating composition used to form the coating. Functional groups that react with the substrate include hydroxyl groups and alkoxy groups. The coating or components of the coating composition may include thiol or episulfide groups. Functional groups of the adhesion promoter that react with the coating or coating composition include epoxy groups and episulfide groups. The coating may form from a reaction between the coating composition and the primer layer and/or between components of the coating composition. The reaction that forms the coating may be catalyzed by a catalyst in the primer layer that was included in the primer composition.

Abstract:
A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.

Abstract:
An optical device includes a support structure configured to retain an optical element using a cured adhesive composition that is disposed between a surface of the support structure and a surface of the optical element, wherein a structured optical particulate material is dispersed throughout the cured adhesive. The structured optical particulate material redirects curing radiation via a scattering mechanism to facilitate curing of portions of the adhesive compositions that cannot be directly exposed to the radiation, thereby facilitating rapid and more thorough curing than could otherwise be achieved without the structured optical particulate material.
