PolyBrite® 70-QS Roof Coating
Brand: Polyglass, IncPolyBrite 70-QS is a premium grade water-based elastomeric coating available in white or as tinted, which cures to form a seamless membrane when applied over the entire roof area.
PolyBrite 70-QS offers the unique ability to extend the life cycle of new and existing roof systems, in addition to keeping the surface cool, providing protection from ultraviolet sun and other weather exposures. PolyBrite 70-QS employs a quick set polymer designed to impact resistance to early rain exposure.
Features- PolyBrite 70-QS can provide some resistance to rain after as little as 20 minutes dry time
- Extends the useful life of the roof
- UV Resistant
- Decreases roof surface temperature, which can reduce energy costs
- Offers high tensile strength and elongation
- Resistant to dirt pick up and is fungal and algal resistant
- Low VOC and non-flammable
