It has excellent adhesion to most commonly used roof substrates such as concrete, asphalt membranes, cement tiles, acrylic, polyurethane paints etc. Shows very low water uptake and crack bridging ability.
Its innovative formula offers fast surface hardness, no tack surface, low dirt pick up, able to keep reflectance properties for longer time. Exhibits high resistance to weather conditions from -20°C/+80°C and excellent resistance to UV radiation and thermal ageing.
Certified by the University of Athens, Department of Physics, as a cool thermoreflective roof coating is a top layer of high reflectivity (visible spectrum reflectance 93%) which improves energy efficiency by reducing cooling costs. Easy application, safe use and no restrictions makes HyRoof Hybrid PU ideal solution for DIY application.
