DETAILED DESCRIPTION - Powder paint composition comprises a vinyl functionalized polysiloxane with a Tg of 80-130 deg. C and prepared from 100-5 mol.% of an organic silane of formula (I) and/or (II) and 5-100 mol.% of a carboxylic acid derivative with at least one double bond. RSiX3 (I) RR'SiX2 (II) R = aminoalkyl, glycidylalkyl, hydroxyalkyl or mercaptoalkyl; R' = aryl or 1 - 4 C alkyl; X = Cl, OH or OR''; and R'' = 1 - 4 C alkyl. An INDEPENDENT CLAIM is included for the coating of substrates by applying the above composition and curing using UV irradiation. USE - For temperature-sensitive substrates, particularly plastic and wood (claimed). ADVANTAGE - The composition can be used at low temperatures, i.e. 80-130 deg. C.de608666patent1998-19841247
