Sunsheetal® is based on polyurethane-acrylic blended elastomeric aqueous polymers. It is a high thermal emittance ceramic coating useful in the world of industrial and commercial buildings, as a roof coating system that has the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, thereby reducing heat transfer to the building. Sunsheetal® is defined as a cool roof coating by virtue of its ability to radiate absorbed, or non-reflected solar energy. Solar heat incident on a roof is dissipated by means of three physical phenomena namely:a fraction of the absorbed heat is conducted to the ground and surrounding buildings a fraction is dissipated by convection to air leading to higher air temperatures, and a fraction is radiated to the sky. As such one has no control over the first two phenomena but the third one, that is, the amount of heat radiated can be maximized by Sunsheetal® roof/ wall coatings that inherently possess high emittance values. Use of Sunsheetal® is particularly useful where the terrace covers an air conditioned space. A higher roof temperature necessarily leads to a higher load on the air-conditioning plant a reduction in roof

       Ready to use single pack system. Repels heat energy & control heat transfer. Reduces air-conditioning running cost up to 40 %. The coating acts as a shield and protects the surface from heat and water. Its film is water resistant and does not support growth of fungus and algae. Does not crack due to wide temperature fluctuation. Cleans up with soap and water.

Special Features
 Sunsheetal® enhances durability of the roof and reduces both building cooling loads and the urban heat island effect.  Sunsheetal® is also an effective alternative to bulk attic insulations under roofs in humid tropical climates. Bulk insulation can be entirely replaced by Sunsheetal® roof coatings that both reflect solar radiation and provide emission to...
