Claims19
A polymer mixture for a multilayer article, wherein the polymer mixture comprises an aqueous binder composition and vulcanized or crosslinked rubber, wherein the aqueous binder composition comprises:
- (a) an acrylic emulsion (co)polymer;
- (b) a crosslinking agent comprising a water-dispersible isocyanate composition;
- and
- (c) a foaming agent;
- and
- wherein the crosslinking agent further comprises an epoxy silane,
- wherein the vulcanized or crosslinked rubber comprises rubber powder having a sieve particle size less than 0.5 mm;
- and the weight ratio of the total solids weight of the acrylic emulsion (co)polymer to the total weight of the vulcanized or crosslinked rubber is from 1:4 to 1:0.5.
