The present disclosure relates to a method of reducing the drying time of a coating composition, comprising adding a multiple-functional composite to the coating composition, wherein the multiple-functional composite is spray-dried composite particles comprising by dry weight based on total dry weight of the spray-dried composite particles, from 60% to 90% of inorganic extenders, from 5% to 25% of inorganic pigments, and from 3% to 20% of water-insoluble polymer particles, wherein the coating composition comprises an aqueous emulsion of acrylic polymer. The present disclosure also relates to a use of multiple-functional composite in reducing the drying time of a coating composition and compositions having reduced drying time. |
