Disclosed is an anti-corrosive coating composition comprising (a) 100 parts by weight of an unsaturated polyester resin, (b) 10 to 100 parts by weight of a glass flake having an average thickness of 0.5 to 5 microns and an average particle size of 100 to 400 microns, or 10 to 70 parts by weight of said glass flake and 10 to 150 parts of scaly metal pigment, (c) 0.1 to 1.0 part by weight of a ketone peroxide and (d) 0.5 to 2.0 parts by weight of a hydroperoxide and/or a peroxy ester. Also disclosed is a process for forming anti-corrosive coatings, which comprises spray-coating the above anti-corrosive coating composition to a thickness of 300 to 1500 microns by using a spray gun having a spray tip diameter of 0.5 to 3 mm.
An anti-corrosive coating composition comprising 100 parts by weight of an unsaturated polyester resin, 10 to 70 parts by weight of glass flake having an average particle size of 100 to 400 microns and an average thickness of 0.5 to 5 microns, 10 to 150 parts by weight of at least one scaly anti-corrosive metal pigment selected from the group consisting of lead pigment and zinc pigment, a member selected from the group consisting of a mixture of 0.1-1.0 parts by weight of a ketone peroxide and 0.5-2.0 parts by weight of a hydroperoxide, a mixture of 0.1-1.0 parts by weight of a ketone peroxide and 0.5-2.0 parts by weight of a peroxyester and a mixture of 0.1-1.0 parts by weight of said ketone peroxide, 0.5-2.0 parts by weight of said hydroperoxide and 0.5-2.0 parts by weight of said peroxyester.
