Thermo-Shield® Roof Coat
Safety Data Sheet
Thermo-Shield® Roof Coat is a high-performance, energy-saving, water-based acrylic roof coating engineered with vacuum ceramic microsphere technology. These microscopic ceramic spheres form sealed air cells that create a seamless, flexible membrane and a highly efficient thermal barrier over the roof surface.
This non-toxic, low-VOC coating bridges hairline cracks, resists harsh chemicals and dirt pickup, and delivers excellent UV protection. With high reflectance and emittance and very low thermal conductivity, Thermo-Shield® Roof Coat significantly reduces heat penetration, thermal shock, and noise transmission—keeping roof surfaces cooler in hot weather while maintaining flexibility in extreme temperatures.
Typical Uses
Roof coating systems where seams, joints, cracks, and penetrations are reinforced with polyester fabric, or anywhere a durable, weather-resistant, membrane-like coating is required.
