Abstract

See full text

This invention relates to coated roofing granules, roofing materials made therefrom, and methods of preparing such coated roofing granules. By coating roofing granules with an aqueous coating that includes water, a silicon-containing oligomer or polymer, and an acrylic resin, coated roofing granules can be prepared that exhibit reduced staining as compared to traditional roofing granules that are treated with petroleum oil.
