    Abstract: This invention provides curable fluoroelastomer compositions comprising: (a) a fluorine-containing polymer or blend of fluorine-containing polymers each comprising interpolymerized units derived from one or more fluorine-containing ethylenically unsaturated monomers; (b) at least one organo-onium compound such as those selected from the group consisting of ammonium, arsonium, phosphonium, stibonium, amino-phosphonium, phosphorane (e.g. triarylphosphorane), iminium, and sulfonium compounds; and (c) one or more aryl, allyl or alkyl carbonate-blocked compound as a crosslinking agents. Methods of curing fluoroelastomer compositions, and articles made therefrom are also described.

    Abstract: Articles having a hydrophobic coating are provided. More specifically, the articles include a substrate, a primer layer of acid-sintered silica nanoparticles, and a hydrophobic hydrocarbon layer attached to the primer layer. The hydrophobic hydrocarbon layer is formed by reaction of the primer layer with a silane compound having a reactive silyl group and a hydrophobic hydrocarbon group. Due to the presence of the primer layer, the silane compounds can be attached to variety of substrates. The articles typically have surface that is easy to clean, smudge resistant, and fingerprint resistant.
