Abstract
Abstract Coating compositions whose binder is an aqueous polymer dispersion produced from 35-70% by weight of styrene and/or a substituted styrene; 30-65% by weight of a fumaric acid diester of 3-6 carbon atoms in the alcohol component; 0-15% by weight of butadiene and/or a substituted butadiene; 0-3% by weight of an α,β-unsaturated carboxylic acid; and 0.2-2% by weight of an amide of an α,β-unsaturated carboxylic acid, possess good resistance to blooming when applied to asbestos cement panels.
