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.
