Surfacing for polymer modified or unmodified bitumen roofing membranes

摘要

Fine quartzite particles with a colored ceramic coating are used for surfacing roofing membranes to enable easier lapping of the roofing membranes while still maintaining necessary UV and heat protection. The roofing membranes may include modified and unmodified bitumen compositions that may be applied to roofing surfaces using heat welding, hot asphalt, cold adhesive, self adhesion and the like.
