摘要： Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.

摘要： 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.
