Process for the production of water-dilutable binders based on air-drying short-oil alkyd resins

摘要: A process for the production of water-dilutable binders based on air-drying short-oil alkyd resins acidified by semiester formation with dicarboxylic acid anhydrides which have numbers from 30 to 70 and hydroxyl 40 120 a content natural unsaturated fatty acids in an amount 15 50 % weight co-condensed natural-resin-modified phenol resol resin 2 10 weight, characterized that 1. molar composition before corresponds polyalcohol/polycarboxylic (anhydride)/monocarboxylic ratio 1 : (0.5-1) (0.3-1), 2. polyalcohols, polycarboxylic resp. their anhydrides, monocarboxylic phenolic are single stage, followed only anhydrides.
