  • Method of finishing with heat insulation coating
    Publication number: 20040137160
    Abstract: The present invention relates to a heat insulating finish coating method which comprises coating by at least one coating a heat insulating coating material by use of (I) a porous-shaped roller or (II) a spray coating gun having a nozzle bore diameter of 0.3 to 15 mm to form a thick film having an uneven coating surface, said heat insulating coating material containing (A) a resin emulsion, (B) a hollow bead having a mean particle size of 1 to 300 &mgr;m and (C) a thickening agent and having a viscosity of 2 to 100 Pa·s, said hollow bead (B) being contained in an amount of 20 to 98% by volume based on a solid content of the heat insulating coating material, said thickening agent (B) being contained in an amount of 0.01 to 5% by weight based on a solid content of the heat insulating coating material.

  • Curable resin composition
    Patent number: 6706818
    Abstract: This invention provides a curable resin composition for one-pack type water-based paint which is readily cured regardless of coating environment, said resin composition comprising copolymer (I) which is produced by the copolymerization of unsaturated group-containing urethane prepolymer (A) which is obtained from a reaction of diisocyanate compound (a), glycol compound (b), carboxyl group-containing glycol compound (c) and hydroxyl group-containing ethylenically unsaturated monomer (d), with maleimide group-containing ethylenically unsaturated monomer (e), carbonyl group-containing ethylenically unsaturated monomer (f) and another ethylenically unsaturated monomer (g), and compound (II) which has, per molecule, two or more same or different functional groups selected from hydrazide group, semicarbazide group and hydrazone group

  • Curing type water base resin composition
    Patent number: 6559231
    Abstract: The present invention relates to a curing type water base resin composition comprising: (I) a copolymer obtained by copolymerizing an ethylenically unsaturated monomer (a) having a maleimide group, an ethylenically unsaturated monomer (b) having a carbonyl group and other ethylenically unsaturated monomer (c) and (II) a compound having two or more groups per molecule which are the same or different and selected from a hydrazide group, a semicarbazide group and hydrazone group and further comprising, if necessary, as an additional component: (III) a copolymer having a carbonyl group and/or (IV) a water base polyurethane resin having a carbonyl group or a hydrazine group.
