    Abstract: 1,196,937. Aqueous synthetic resin baking enamel. BADISCHE ANILIN- & SODAFABRIK A.G. 17 Aug., 1967 [18 Aug., 1966], No. 37846/67. Heading C3R. [Also in Division B2] An aqueous baking enamel contains (a) 4.5 to 70 p.b.w. water-compatible aminoplast or phenolic resole precondensate, (b) 95 to 30 p.b.w. incompletely condensed alkyd resin having unesterified COOH and OH groups which has been rendered water-compatible with ammonia or a nitrogenous organic base, and, as a flow improver, (c) 0.5 to 5 p.b.w. of an ether of boiling point between 100‹ and 300‹ C. and formula R 1 -O-R 2 where R 1 and R 2 are hydrocarbon radicals, the total number of C atoms in the hydrocarbon radicals being 9 to 20; (a) + (b) + (c) total 100 p.b.w. Several ethers are mentioned. The enamels may be coated on sheet iron and baked at 120‹ to 190‹ C. for 10 to 100 minutes. In the examples : (a) is 25 p.b.w. of a commercial 70% solution of hexamethoxymelamine in propanol/water, and (b) 73 p.b.w. of a commercial 55% solution in glycol ether/water of a dehydrated castor oil modified phthalic anhydride/trimethylol propane alkyd brought to pH 7 to 8 with triethylamine, (c) is di-2-ethylhexyl, dinonyl, or 2-ethylhexen-(1)-yl 2-ethylhexyl ether and the enamels also contain 40 or 50 p.b.w. of water.

    Abstract: 1,199,598. Aqueous synthetic resin baking enamel. BADISCHE ANILIN- & SODAFABRIK A.G. 17 Aug., 1967 [18 Aug., 1966], No. 37845/67. Heading C3R. [Also in Division B2] An aqueous baking enamel contains (a) 4À5 to 70 p.b.w. water-compatible aminoplast or phenolic resole precondensate, (b) 95 to 30 p.b.w. incompletely condensed alkyd resin having unesterified COOH and OH groups which has been rendered water-compatible with ammonia or a nitrogenous organic base, and, as a flow improver, (c) 0À5 to 5 p.b.w. of an acetal of boiling point between 100‹ and 300‹ C. and formula R 1 O-CH.R 3 -OR 2 where R 1 and R 2 are hydrocarbon radicals and R 3 is H or a hydrocarbon radical the total number of C atoms in the hydrocarbon radicals being 7 to 26. (a) + (b) + (c) total 100 p.b.w. Several acetals are mentioned. The enamels may be coated on sheet iron and baked at 120‹ to 190‹ C. for 10 to 100 minutes. In the examples (a) is 25 p.b.w. of a commercial 70% solution of hexamethoxymelamine in propanol/water and (b) 73 p.b.w. of a commercial 55% solution in glycol ether/water of a dehydrated castor oil modified phthalic anhydride/trimethylol propane alkyd brought to pH 7 to 8 with triethylamine, (c) is di-2-ethylhexylisobutyraldehyde, diisobutyl-2-ethylhexanol or di-2-ethylhexylformaldehyde acetal and the enamels also contain 40 or 50 p.b.w. of water.
