摘要：
The present invention provides compositions that enable excellent early hardness development in coating applications, the compositions comprising a blend of one or more acrylic emulsion copolymer, pA, having a Tg of 20° C. or higher, and one or more acrylic emulsion copolymer, pB, having a Tg at least 15° C. lower than that of pA, together with one or more additive chosen from a coalescent having a normal boiling point no greater than 300° C., a naturally derived plasticizer, and mixtures thereof. The compositions may be ambient curable.
