Abstract
Official abstract text for this publication.
The present invention provides elastomeric roof coatings and aqueous coating compositions of (i) an acrylic emulsion copolymer that comprises (ii) a reductant and has a high molecular weight, (iii) a combination of a hydrophilic polymeric dispersant and a pigment, extender or filler, and (iv) a multivalent transition metal ion or multivalent transition metal ion compound or salt. The composition and coating provide excellent swelling resistance and a balance of tensile and elongation in an acrylic roof coating composition.
First claim
Opening claim text (preview).
We claim: 1. An aqueous composition for coating roofing substrates comprise (i) one or more emulsion copolymer having a glass transition temperature (Tg) of from −45° C. to −10° C. having a weight average molecular weight of from 100,000 to 2,000,000, the emulsion copolymer being the copolymerization product of a monomer mixture of (a) from 74 wt. % to 97.75 wt. % of one or more C 4 to C 6 alkyl(meth)acrylates or a mixture thereof with up to 20 wt. % of a C 7 to C 24 alkyl(meth…
