ABSTRACT:
Roofing granules having surfaces treated with an oil and an elastomeric rubber. The elastomeric rubber can be an organic block copolymer having elastomeric and nonelastomeric repeating units. The oil and rubber are applied to the roofing granules' surfaces as a thin film. The thin film of oil and rubber impedes granule staining from oils in asphalt roofing materials, and reduces dust formation during granule handling. Also disclosed is a roofing shingle and a process for making the roofing granule composition.
