Abstract: A method for forming a coating on a substrate using an atmospheric pressure plasma discharge. The method comprises introducing an atomized liquid and/or solid coating-forming material into an atmospheric pressure plasma discharge and/or an ionized gas stream resulting therefrom, and exposing the substrate to the atomized coating-forming material. The application also described a method for polymerizing a polymer forming material, and further to apparatus for forming a coating on a substrate.

Abstract: A method of coating a surface of a low surface energy substrate by exposing the substrate to a silicon containing compound in liquid or gaseous form selected from a chlorine terminated polydimethylsiloxane, direct process residue, ZxSiR54−x, SinY2n+2 or a mixture thereof, where each Z is a chloro or alkoxy group and each R5 is an alkyl group or substituted alkyl group, x is 1 to 4, n is from 2 to 10 and each Y may be selected from a chloro, fluoro, alkoxy or alkyl group but at least two Y groups must be chloro, or alkoxy groups or a mixture thereof and forming a grafted coating layer on the substrate surface and subsequently post-treating the grafted coating layer by oxidation or, reduction, which is preferably utilising a plasma or corona treatment, in particular atmospheric pressure glow discharge or dielectric barrier discharge.

Abstract: A curable composition comprises a siloxane polymer, filler and a curing agent which is capable of effecting the cure when heated, wherein the curing agent comprises bis(2,4-difluorobenzoyl) peroxide or bis(2,6-difluorobenzoyl) peroxide. The composition is curable to a elastomeric condition by heat.
