Abstract
Official abstract text for this publication.
The present invention provides a composition comprising i) an acrylic polymer dispersion and ii) a polyurethane/acrylic hybrid; wherein the acrylic polymer has a Tg from 25° C. to 80° C.; the polyurethane/acrylic hybrid has a Tg from −55° C. to 0° C.; and the minimum film formation temperature of the composition is lower than 10° C. The present invention further provides a coating comprising the composition.
First claim
Opening claim text (preview).
1 . A composition comprising i) an acrylic polymer dispersion and ii) a polyurethane/acrylic hybrid; wherein the acrylic polymer has a Tg from 25° C. to 80° C.; wherein the polyurethane/acrylic hybrid has a Tg from −55° C. to 0° C.; and wherein the composition has a minimum film formation temperature of lower than 10° C. 2 . The composition according to claim 1 , wherein acrylic monomers in the acrylic polymer and in the polyurethane/acrylic hybrid are different acrylic compounds. 3 . The composition according to claim 1 , wherein the acrylic polymer further comprises, as polymerized units, a diacetone acrylamide. 4 . The composition according to claim 1 , wherein the polyurethane/acrylic hybrid further comprises, as polymerized units, a diacetone acrylamide. 5 . The composition according to claim 1 further comprising an adipic dihydrozide. 6 . The composition according to claim 1 , wherein the acrylic polymer has a Tg from 28° C. to 70° C. and the polyurethane/acrylic hybrid has a Tg from −45° C. to −5° C. 7 . A coating comprising a composition comprising i) an acrylic polymer dispersion and ii) a polyurethane/acrylic hybrid; wherein the acrylic polymer has a Tg from 25° C. to 80° C.; wherein the polyurethane/acrylic hybrid has a Tg from −55° C. to 0° C.; and wherein the composition has a minimum film formation temperature of lower than 10° C. 8 . The coating according to claim 7 , wherein acrylic monomers in the acrylic polymer and in the polyurethane/acrylic hybrid are different acrylic compounds. 9 . The coating according to claim 7 , wherein the acrylic polymer further comprises, as polymerized units, a diacetone acrylamide. 10 . The coating according to claim 7 , wherein the polyurethane/acrylic hybrid further comprises, as polymerized units, a diacetone acrylamide. 11 . The coating according to claim 7 , wherein the composition further comprises an adipic dihydrozide. 12 . The coating according to claim 7 , wherein the acrylic polymer has a Tg from 28° C. to 70° C. and the polyurethane/acrylic hybrid has a Tg from −45° C. to −5° C.
