  • Antifouling coating composition and uses of the same
    Patent number: 8840910
    Abstract: There is provided an antifouling coating composition capable of forming an antifouling coating film which has stable coating film consumption degree on ships, underwater structures and the like and which exhibits excellent antifouling property over a long term. The antifouling coating composition includes a hydrolyzable copolymer (A) and an antifouling agent (B), wherein the hydrolyzable copolymer (A) is, e.g., a metal salt bond-containing copolymer having a component unit derived from a monomer (a21) represented by the general formula (II): CH2?C(R2)—COO-M-O—CO—C(R2)?CH2??(II) [In the formula (II), M is zinc or copper, and R2 is a hydrogen atom or a methyl group], and a component unit derived from other unsaturated monomer (a22) copolymerizable with the monomer (a21), and wherein the antifouling agent (B) includes at least medetomidine.
    Type: Grant

  • SILYL (METH) ACRYLATE COPOLYMERS, PROCESSES FOR PREPARING THE SAME, ANTIFOULING PAINT COMPOSITIONS CONTAINING THE SILYL (METH) ACRYLATE COPOLYMERS, ANTIFOULING COATING FILMS FORMED FROM THE ANTIFOULING PAINT COMPOSITIONS, ANTIFOULING METHODS USING THE ANTIFOULING PAINT COMPOSITIONS, AND HULLS OR UNDERWATER STRUCTURES COATED WITH THE ANTIFOULING COATING FILMS
    Patent number: 6458878
    Abstract: Disclosed is a silyl (meth)acrylate copolymer which comprises 20 to 80% by weight of (a) silyl (meth)acrylate constituent units (I), 0.01 to 40% by weight of (b) acrylic unsaturated monomer constituent units (II) and 5 to 79.9% by weight of Ĉ unsaturated monomer constituent units other than the constituent units (a) and (b). Also disclosed is a process for preparing the silyl (meth)acrylate copolymer, an antifouling paint composition comprising the copolymer, a coating film formed from the paint composition, a hull with the coating film and an antifouling method using the paint composition.
