Abstract
EP 1186640 A UPAB: 20020815 NOVELTY - A coating composition comprises: (a) a silane or its (partial) condensate; (b) an IR-reflecting pigment mainly of particle size 1-50 mu ; and (c) a solvent and dispersant and is such that (i) the pigment amount makes the coating impermeable to visible-range light and (ii) a further component produces such impermeability. DETAILED DESCRIPTION - A coating composition comprises: (a) a silane of formula (I) or its (partial) condensate; (b) an IR-reflecting pigment mainly of particle size 1-50 mu ; and (c) a solvent and dispersant and is such that (i) the pigment amount makes the coating impermeable to visible-range light and (ii) a further component produces such impermeability. XaRbSiR14-a-b (I) X = a hydrolysable group; R = optionally substituted alkyl, alkenyl, aryl, alkaryl or aralkyl; R1 = an organic residue linked to the Si atom via C and containing a reactive group; a = 1, 2 or 3; b = 0, 1 or 2. USE - As an oil- and water-repellent (i.e. self-cleaning) paint for internal or fade use. ADVANTAGE - The coating combines outstandingly high oleo- and hydrophobicity with heat-reflecting properties while being workable by wet lacquer technologies and self-hardening. Further, it can contain little or no solvent and can be viscosity-adjusted with water.
