Die vorliegende Erfindung betrifft Antifoulingmittel, ein Verfahren zur Herstellung und deren Verwendung sowie daraus hergestellte Antifoulingbeschichtungen. An antifouling agent comprises a polyfunctional carbosilane or siloxane (I) or its condensation product. An antifouling agent contains: (A) at least one polyfunctional carbosilane and/or siloxane of formula Q((CH2)mSi(R1)nX3-n)p (I) and/or its (partial) condensation product; and optionally (B) at least one alkoxysilane; (C) at least one alkoxysilane; (D) a solvent and/or water; (E) inorganic nanoparticles: and/or (F) other additives. R1 = 1-18C alkyl and/or 6-20C aryl; X = OH, 1-4C alkoxy, 6-20C aryloxy or 1-6C acyloxy; n = 0-2; m = 2-6; p = at least 2; Q = llinear or cyclic silane or siloxane or hydrocarbyl (optionally substituted by at least one group containing O, N, S or P). Independent claims are included for: (a) preparation of the composition by mixing components (A)-(F); (b) the use of the composition for the preparation of antifouling coatings; (c) antifouling coatings obtained by applying the composition to a substrate; and (d) the preparation of antifouling coatings by applying the composition to articles to be protected.
