one component polyurethane resin for building heat reflection

Descriptions

Heat is a necessary condition for human’s survival, but too much energy from sunshine and fuel becomes a pressure and burden. The accident and death toll caused from over temperature is innumerable every year in the world. Every summer, the energy consumption of air conditioning, fans and other cooling equipment occupied 30% of all the energy amount whole year which is a huge waste. The environment friendly building waterproof energy efficient cold coating developed by SWD Urethane Co., USA in 1990s can not only insulate heat and lower the building temperature, but also provide a waterproof protection layer for the building roof and wall surface. The service can reach more than 15 years and it has been widely applied in Europe and America.

Characteristics

Applied with unique formula and scientific process, SWD8005 coating takes the one component environment friendly water base macromolecule prepolymer resin as main materials. The coating film is dense, with excellent sealing and penetration resistance performance and high adhesive strength with substrate. It has high reflection rate against sunlight and hemispherical emissivity that has super heat reflection which able to adjust the temperature more than 10°C. With high performance of waterproof, erosion resistance and stain resistance, it can bear long-term outdoor application with no peel off, pulverization and yellowing. It is green and environment friendly will do no harm during application.
