Abstract

A process for the preparation of a coating composition based on an aqueous thermosetting acrylic enamel comprising from 10 to 60% by weight of film-forming constituents and correspondingly from 90 to 50% by weight of water and up to 20% by weight of a solvent of the film-forming constituents, whose process is characterized by mixing: (1) 60 to 90% by weight, calculated on the weight of the film-forming constituents, of an acrylic polymer prepared by a solution polymerization and with a uniformity factor of at least 75% and consisting essentially of polymerized units of (a) 20-60% by weight, calculated on the weight of the acrylic polymer, of a hard constituent that is methyl methacrylate or a mixture of methyl methacrylate and styrene in which styrene constitutes up to 40% of the weight of the polymer acrylic; (b) 20-40% by weight, calculated on the weight of the acrylic polymer, of a soft acrylic constituent that is an alkyl acrylate of 2 to 12 carbon atoms in the alkyl group, an alkyl methacrylate of 4 to 12 atoms carbon in the alkyl group or a mixture of the aforementioned acrylate and methacrylate; (c) 4-20% by weight, calculated on the weight of the acrylic polymer of a hydroxy constituent that is a hydroxyalkyl methacrylate or a hydroxyalkyl acrylate or a mixture thereof, where the alkyl groups have 2 to 4 atoms of carbon; (d) 4-20% by weight, calculated on the weight of the acrylic polymer of an unsaturated carboxylic acid; where the polymer has a carboxyl to hydroxyl ratio between 1: 0, 2 and 1: 1.8, an acid number of approximately 35-150 and a weight average molecular weight of 5,000-80,000; and (2) from 10 to 40% by weight, calculated on the weight of the film-forming constituent, of a water-dispersible, alkylated melamine-formaldehyde resin containing 1 to 4 carbon atoms in the alkyl groups; and the composition is at least partially neutralized with a water soluble amine to provide a pH of about 6-9.
