  • Process for forming a corrosion resistant coating
    Patent number: 4514445
    Abstract: A process for forming a corrosion resistant coating, which comprises (i) a step of priming a solvent-type coating composition on a substrate and drying it to form a prime coat, and (ii) a step of coating a radical-polymerizable and oxidation-polymerizable, room temperature curing type solventless coating composition on the prime coat and polymerizing it to form a cured coating.
    Type: Grant
    Filed: November 8, 1983
    Date of Patent: April 30, 1985
    Assignees: Dai Nippon Toryo Co., Ltd., Mitsubishi Yuka Fine Chemicals Co., Ltd.

  • Process for forming a corrosion resistant coating
    Patent number: 4508767
    Abstract: A process for forming a moisture resistant coating, which comprises:(i) a step of priming a coating composition on a substrate and drying it to form a prime coat,(ii) a step of coating thereon a radical-polymerizable and oxidation-polymerizable, room temperature solventless coating composition containing a scaly pigment and polymerizing it to form a cured intermediate coat, and(iii) a step of finish coating thereon an air-drying finish coating composition and drying it to form an finish coat.
    Type: Grant
    Filed: November 30, 1983
    Date of Patent: April 2, 1985
    Assignees: Dai Nippon Tokyo Co., Ltd, Mitsubishi Yuka Fine Chemicals Co., Ltd.

  • Process for forming a corrosion resistant high-build type coating
    Patent number: 4505954
    Abstract: A process for forming a corrosion resistant high-build type coating, which comprises (i) a step of priming on a substrate a coating composition comprising (a) 100 parts by weight of a mixture composed of from 99.9 to 60% by weight of a vegetable oil and/or a phthalic alkyd resin, and from 0.1 to 40% by weight of tricyclodecene and/or its derivative, and (b) from 1 to 500 parts by weight of at least one member selected from the group consisting of an oxyacid salt, and metal lead and its oxide and salt, followed by drying it to form a prime coat, and (ii) a step of applying thereon a radical-polymerizable and oxidation-polymerizable, room temperature curing type solventless coating composition, and polymerizing it to form a cured coating film.

  • Oil-modified alkyd resin compositions
    Patent number: 4147675
    Abstract: A paint composition comprises (A) 30 to 70 percent by weight of an oil-modified alkyd resin of an oil length of 30 to 70 percent which has been modified with sorbic acid, crotonic acid, or 2-(.beta.-furyl) acrylic acid, the content of which is 0.5 to 30 percent by weight and (B) 70 to 30 percent by weight of a polymerizable monomer in which the oil-modified alkyd resin is dissolved.
