HEAT REFLECTOR (KEN-HW-704) (Heat Resistance) Heat and waterproof, KEN- HW-704, is a heat reagestens acrylic waterproofing coating. It provides an excellent waterproof barrier which remains unaffected by expansion and contraction movements caused by temperature difference in the roof surfaces. By reducing heat transfer into the buildings and keeping the interiors cool it assist in depletion of electricity usages. Its excellent crack bridging ability obstruct water penetration through the hairline cracks developed on the roof surfaces. The coating provides the twin benefit of thermal conductivity reduction while making surface impervious to the water. It extends the roof service life
