• Coating varnish composition and antifouling coating composition
  申请人：HITACHI CHEMICAL CO., LTD.

  公开号：EP0608132A1

  公开（公告）日：1994-07-27

  The invention provides a coating varnish composition comprising (A) a polymer obtained by polymerizing (a) at least one unsaturated acid anhydride and (b) at least one other unsaturated monomer, and (B) at least one additive selected from triazole derivatives, benzothiazole derivatives, thiadiazole derivatives, polyethers and carboxylic acid anhydride derivatives and an antifouling coating composition comprising said coating varnish and an antifouling agent containing a coppercompound as major component. Using such compositions the risks of poisoning associated with organotin copolymers are avoided and there are obtained coatings of a coating consuming property and antifouling performance comparable with those of the organotin copolymers which do not gel even when mixed with a copper compound.

  本发明提供了一种涂料清漆组合物，该组合物包含(A)通过聚合(a)至少一种不饱和酸酐和(b)至少一种其他不饱和单体而得到的聚合物，和(B)至少一种选自三唑衍生物、苯并噻唑衍生物、噻二唑衍生物、聚醚和羧酸酐衍生物的添加剂，以及一种防污涂料组合物，该组合物包含上述涂料清漆和一种以铜化合物为主要成分的防污剂。使用这种组合物可以避免与有机锡共聚物有关的中毒风险，并获得涂层消耗特性和防污性能与有机锡共聚物相当的涂层，即使与铜化合物混合也不会凝胶。
