Patent ID: 7468399

Claim:
An anti-fouling or fouling release condensation curing organopolysiloxane composition comprising in admixture, (A) a base polymer in the form of a diorganopolysiloxane having at least two silicon atom-bonded hydroxyl and/or hydrolyzable groups in a molecule, (B) a silane having at least two hydrolyzable groups in a molecule and/or a partial hydrolytic condensate thereof, and (C) 0.01 to 30% by weight based on component (A) of an ionic liquid, wherein said ionic liquid consists of a quaternary ammonium cation selected from the group consisting of a methyltri-n-octylammonium cation, an ethoxyethylmethylpyrrolidinium cation, and an ethoxyethylmethylmorpholinium cation and an anion selected from the group consisting of AlCl 4 − , Al 3 Cl 8 − , Al 2 Cl 7 − , ClO 4 − , PF 6 − , BF 4 − , CF 3 SO 3 − , (CF 3 SO 2 ) 2 N − , and (CF 3 SO 2 ) 3 C − and said ionic liquid has a melting point in the range of −50° C. to 20° C.
