Blends of acrylic latices and polyurethane dispersions for coatings
A waterborne coating composition contains a film forming binder dispersed in an aqueous carrier; wherein the binder is an admixture including (A) about 40-60% by weight of an acrylic silane polymer derived from a monomer blend including alkyl (meth)acrylate monomers and at least one silane containin...

| Zusammenfassung: | A waterborne coating composition contains a film forming binder dispersed in an aqueous carrier; wherein the binder is an admixture including (A) about 40-60% by weight of an acrylic silane polymer derived from a monomer blend including alkyl (meth)acrylate monomers and at least one silane containing alkyl (meth)acrylate monomer; and (B) about 60-40% by weight of a polyurethane/acrylic hybrid dispersion. The composition is useful for plastic and metal substrates. |
