摘要:
An antifouling paint composition containing, as a vehicle component, a resin obtained by grafting a hydrolyzable polyester (A) having (a) an oxyacid and/or its condensate, (b) a polybasic carboxylic acid containing no hydroxyl group and/or its acid anhydride and (c) a polyhydric alcohol reacted so that the equivalent ratio of the total hydroxyl groups in (a) and (c) to the total carboxyl groups in (a) and (b) is from 1/0.9 to 1/1.1, to a vinyl copolymer (B') containing, as a constituting component, at least 10 mol% of a polymerizable unsaturated monomer having a functional group reactive with a hydroxyl group in (A), said resin having free carboxyl groups blocked by a blocking agent so that the acid value is not higher than 20.
摘要:
An antifouling paint composition containing, as a binder, a mixture comprising (A) from 20 to 80 wt% of a water-insoluble and hydrophobic acrylic resin having a glass transition temperature of from -50 to 0°C and (B) from 80 to 20 wt% of a metal salt of rosin.
摘要:
The present invention relates to an antifouling coating composition comprising:
(a) a vehicle comprising a hydrophobic resin (A), a slightly soluble resin (B) and a hydrophilic resin (C), and (b) a copper alloy powder as an antifouling agent comprising from 3 to 25% by weight of nickel and/or manganese, from 0.1 to 1.5% by weight of iron and the rest being copper, and (c) if necessary, one of zinc oxide, germanium oxide and a flake pigment.

摘要:
A cold-setting aqueous emulsion paint comprising a pigment and an aqueous emulsion resin consisting essentially of a copolymer of (a) a polymerizable monomer of the formula (I): wherein R is a hydrogen atom or a methyl group, and n is 1 or 2, (b) a polymerizable monomer having a carboxyl group and an ethylenic double bond, and (c) a polymerizable monomer having an ethylenic double bond copolymerizable with the above polymerizable monomers (a) and (b).
摘要:
A method for sealing a zinc-aluminum pseudo alloy spray coating, which comprises forming a zinc-aluminum pseudo alloy spray coating on a substrate to be spray-coated, and then sealing the surface of the coating with a chromium-free sealing material containing phosphoric acid in an amount of from 0.1 to 7 wt%.
