CLASS: IC: C08G010-04; C08L061-18. APPLICATION: JP 82-57054 5 Apr 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Coating materials having good flexibility and elec. resistivity are prepd.Several substances with their cas registry numbers 108-31-6 and 1330-20-7 may be metioned in this study. by treating arom. hydrocarbon-HCHO resins with polyols, unsatd. dicarboxylic acid derivs., and vegetable oils and thinning with vinyl compds. Thus, a mixt. of HCHO-xylene copolymer 40, propylene glycol 20, maleic anhydride 20, and tall oil 20 parts was heated 3 h at 200°. The above product (100 parts) was thinned with 80 parts styrene, applied to tinplate, and cured to give a coating with good adhesion to the substrate. .
