Aqueous acrylic textured layer forming compositions useful as top coats for synthetic sport surfaces

A two-component aqueous textured layer forming composition comprising:

• a first component of (i) an acrylic emulsion copolymer blend of (a) a first acrylic emulsion copolymer A having a calculated glass transition temperature (calculated Tg) of from −60 to −5° C. and, (b) a second acrylic emulsion copolymer B having a calculated Tg of from 15 to 60° C. in a solids weight ratio of copolymer A:copolymer B of from 25:75 to 90:10;
• (ii) vulcanized or crosslinked rubber granules, in an amount wherein a solids weight ratio of the acrylic emulsion copolymer blend:vulcanized or crosslinked rubber granules ranges from less than 1:4 to 1:9, (iii) one or more polyalkylene oxides having a viscosity average molecular weight of from 400,000 to 5,000,000;
• and (iv) one or more high boiling alcohols having a normal boiling point of from 170 to 315° C., and, further, having a formula MW of 100 to 250;
• and, as a second component, (v) a crosslinking agent comprising both an aliphatic water-dispersible polyisocyanate composition and an epoxy silane.
