Abstract
The present invention provides two-component aqueous textured layer forming compositions useful for forming flexible top coat layers for sports surfaces. The compositions comprise vulcanized or crosslinked rubber granules, for example, EPDM rubber, a soft:hard acrylic emulsion copolymer blend in a solids weight ratio to vulcanized or crosslinked rubber granule solids that ranges from less than 1:4 to 1:9, a polyalkylene oxide rheology modifier, one or more high boiling alcohols and, as a separate component, an aqueous dispersion of an aliphatic polyisocyanate as well as an epoxy silane. The vulcanized or crosslinked rubber granules may have a sieve particle size of 8 mm or less. The inventive top coat layers have enhanced tensile strength and elongation as well as improved pot life and color stability.
