Abstract: A composition which provides a coating film having excellent foul releasing property is disclosed. The composition comprises, based on the solid contents of the composition: (A) 20 to 80 weight % of a resin which has a polydialkylsiloxane unit and an epoxy resin unit within its structure; (B) 0.1 to 5 weight % of an amino silane; (C) 0.5 to 5 weight % of a hydrophilic additive; and (D) 0.1 to 5 weight % of a catalyst. A coating, e.g. a coating film, formed from the composition generally has an amphiphilic surface. Thus, the composition is suitable for coatings which prevent both hydrophobic and hydrophilic fouling.

Abstract: Embodiments of the present disclosure are directed to a polymeric composition comprising the cross-linked reaction product of an ionomer and a silane crosslinking agent. The ionomer may include an E/X/Y polymer where E is an ethylene monomer, X is α,β-ethylenically unsaturated carboxylic acid comonomer having 3 to 8 carbons, or its ester, and Y is alkyl acrylate or dicarboxylic acid comonomer. The ionomer comprises from 1 to 30 wt. % of X and from 0 to 40 wt. % of Y. At least a portion of the carboxyl groups of X and optionally Y are neutralized with a metal cation. The silane crosslinking agent has a formula Z((CH2)aSi(OR)b)c. Z is a mono-functional reactive group, R is an alkyl group having 1 to 4 carbon atoms or a hydrogen atom, a is from 1 to 4, b is 3, and c is from 1 to 2.
