Molawan ThermoCool is a cost effective pre-painted steel developed to provide durable material for exterior applications with High Thermal reflectivity. The paint is a thermal reflective paint, consisting of special ceramic pigments, applied on a Galvanized substrate of 90 gsm minimum zinc coating, with paint film thickness of 20 microns on weathering side. This product is designed to lower the surface temperature of buildings when used for roofing/wall applications and provides thermal comfort and energy savings.
Substrate
Galvanized steel, mimimum G30(90 GSM).
Grade : CS Type A&B, FS Type A&B, SS33, SS40 & SS50
Typical Uses
Roofing and Walling , Sandwich Panels, Cold Rooms etc.
