Sunshield is a water-borne combination of high-performance duo of elastomeric acrylics and resin additives, which produces a tough, yet flexible coating film. It combines four different ceramics that provide both heat reflectivity and heat-blocking properties. Sunshield is a flexible membrane with low permeability that can greatly reduce expansion and contraction of a roof. Sunshield’s blend of resin additives produce a flexible coating membrane that can be applied directly to any surface. It also prevents corrosion and surface deterioration. Although durable and offering solar blocking performance, Sunshield does not give the same benefits as Super Therm®.
