    摘要: The present invention provides compositions for use as elastomeric roof coatings having excellent infrared (IR) reflectivity which comprise (i) one or more elastomeric copolymer having a measured glass transition temperature (measured Tg) of from −100 to 0° C. and one or more mesoporous filler, preferably a mesoporous filler that is substantially free of organic groups or residues, the mesoporous filler chosen from mesoporous silica, mesoporous aluminosilicates and mesoporous alumina, wherein the composition has a pigment volume concentration (% PVC) of from 0.1 to 15%. Such compositions provide aqueous or solvent borne clearcoats that can go over existing, already painted or colorcoated roof or wall substrates to preserve their finish or appearance.

    摘要: A process comprising: A) contacting one or more of sources of silicon oxide, selected from water sol-uble.silica sources arid alkali metal silicates, with an aqueous reaction medium, comprising one or more nonionic surfactants and thereby forming mesoporous structures comprising crosslinked silicon oxide units, wherein said cross-linked silicon oxide units have pores of about 1 to about 100 nanometers and wherein the aqueous reaction medium exhibits a pH of about 0 to about 4.0; B) exposing the aqueous reaction medium containing the mesoporous structures to elevated temperatures for a time sufficient to achieve the desired structure and pore size. Preferred water soluble silica sources comprise silicic acid, or po!ysilicic acids, The aqueous reaction, medium is prepared by combining one or more nonionic surfactants and water, theteby forming an aqueous, reaction medium. comprising micelles. Preferably, the aqueous reaction medium further comprises, a. micelle swelling agent capable of swelling micelles formed by the surfactant in the aqueous reaction medium. In one embodiment the process forms structures with struts comprised of crosslinked silicon oxides which connect at least some of the pore forming structures.
