A LIQUID COATING COMPOSITION COMPRISING: (a) 5 TO 40 PARTS BY WEIGHT OF AMINO RESINS, (b) 95 TO 60 PARTS BY WEIGHT OF VINYL-MODIFIED ALKYD RESINS, AND (c) AN ORGANIC SOLVENT OR A MIXTURE OF THE ORGANIC SOLVENT AND WATER, WHEREIN SAID VINYL-MODIFIED ALKYL RESINS ARE OBTAINED BY GRAFT-POLYMERIZING A VINYL MONOMER OR A MIXTURE OF VINYL MONOMERS ONTO ALKYD RESINS AFTER SAID ALKYD RESINS ARE OBTAINED BY REACTING POLYALCOHOL WITH CARBOXYLIC ACIDS, SAID ALKYD RESINS, CONTAINING 5 TO 60% BY WEIGHT OF HEXAHYDROPHTHALIC ACID AND/OR ITS ANHYDRIDE.
摘要:
An oil modified unsaturated polyester resin in which at least one hydroxyl group is left at a terminal of its molecule, having a number average molecular weight of from about 1,000 to about 4,000 and acid value of from 5 to 60 is made to react with at least one diisocyanate compound having from 0.2 to 1.2 equivalent of isocyanato group with respect to 1 equivalent of hydroxyl group of said unsaturated polyester resin to produce an urethanated unsaturated polyester resin having a molecular weight of from about 2,000 to about 20,000.
摘要:
POLYMERIZABLE UNSATURATED AND URETHANATED COMPOUNDS USEFUL FOR COATING COMPOSITIONS WHEREBY SAID POLYMERIZABLE UNSATURATED AND URETHANATED COMPOUNDS ARE OBTAINED BY REACTING DIISOCYANATE COMPOUNDS WITH REACTION PRODUCTS WHICH ARE OBTAINED BY REACTION DICARBOXYLIC COMPOUNDS WITH POLYMERIZABLE UNSATURATED MONOGLYCIDYL MONOMERS. THE HARDENED MATERIALS OBTAINED FROM SAID POLYMERIZABLE UNSATURATED AND URETHANATED COMPOUNDS ARE EXCELLENT IN THEIR CHEMICAL AND MECHANICAL PROPERTIES.
