SOLARTEC is a purpose-made, solar reflective coating that incorporates a synthetic copolymer-based resin containing inert titanium-based pigments, proprietary fillers and special UV barrier pigments in an ethanol solution. The coating can be applied to a variety of surfaces including flat and pitched asphalt, bituminous membrane, concrete, ceramic tiles, brick and plaster, metal roofing sheets etc.
The application of SOLARTEC offers several advantages. Since the absorption of solar energy by buildings is significantly reduced, structural movements are minimized and air-conditioning costs are lowered.
SOLARTEC combats infrared and ultraviolet degradation of asphalt, bituminous membranes and metal roofs. Also, the roof replacement and recoating cycle is extended. The durability of the coating is not affected by the ponding of water. Further, there is a large reduction in the loading on flat roofs.
SOLARTEC is easy to apply and maintain. In addition, repaired areas can be easily and economically recoated.
The pigments incorporated within SOLARTEC are chemically stable and remain effective even under the most demanding environmental conditions. The coating is resistant to alkalis, acids, salt spray, fungi and algae.
SOLARTEC is available in three standard colours – white, green and grey. The exact degree of solar reflectivity, measured across the entire solar spectrum, achieved by SOLARTEC White, SOLARTEC Green and SOLARTEC Grey, is 85%, 75% and 65% respectively. Other colours are available upon request. SOLARTEC is available in 5 kg, 10 kg and 20 kg drums.
Specially developed pigments and proprietary fillers in SOLARTEC make the surface a good reflector of solar radiation covering the full spectrum, from ultraviolet to infra-red. It is also a good radiator of infra-red heat, that is, it readily emits any collected heat. SOLARTEC thus becomes an external ‘heat rejecting’ membrane, in thicknesses of 50 microns to 100 microns.
Studies conducted in
In 2001, Energy Testing Services Ltd, UK studied the effects of solar reflective coatings applied to roofs in Singapore, on the cooling loads on buildings, in accordance with the Singapore Building Control Regulations, for three roof structure categories - heavy, medium and light. Results tabulated throughout the whole year, showed a 60% to 65% reduction in solar heat gain, due to the coatings.
SOLARTEC has been widely used in projects around the world for more than 15 years.In
At the former Shell Recreation Club, the temperature reduction observed at the underside of the galvanized roof, was 10º C to more than 20º C during the hottest part of the day, as a result of the SOLARTEC application. On the topside surface of the concrete roof slab at the Nanyang Technological University Estate Office, a difference of 13.4º C was recorded.
