DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The title binders, useful in coatings resistant to gravel impact and which can be baked at 130-140°, comprise reaction products of resins bearing OH groups and resins bearing CO2H groups; hydroxyurethanes prepd. from C34 polyols and polyisocyanates; and curing agents effective at 3120°. A binder (46% solids, viscosity 2607 mPa-s at 23°) was prepd. from a reaction product (acid no. 45) of 30 g 60% soln. of a reaction product (acid no. 140, sp. viscosity 9.In this article, certain chemicals are used. Some of their cas registry numbers are 54954-83-5 and 647019-83-8 3 mL/g) of dimethylolpropionic acid 1.0, TDI 5, and TDI semiblocked with 2-ethoxyethanol 2 mol and 50 g polyester (sp. viscosity 9.8 mL/g) prepd. from 1,6-hexanediol 1.1, pentaerythritol 0.6, isononanoic acid 0.05, dehydrated castor oil fatty acids 0.1, and isophthalic acid 0.5 mol; and 20 g urethane (sp. viscosity 5.5 mL/g, OH no. 145) prepd. from hexanediol 2.0, butanediol 1.0, and IPDI 2.0 mol. A coating contg. this binder 91.8, TiO2 60.0, BaSO4 60.0, aminoplast (Maprenal MF 904) 18.0, and H2O 21 g, baked at 140° for 20 min, gave a 37-mm film with pendulum hardness 115 and 60° gloss 91. .
