STWD8005 one component heat reflective building waterproof cold coating took one component water based polymer resin as main raw material, produced with advanced technology process. It reflects high solar light ratio and high hemispherical emissivity, it has high heat reflective effect that can make the heat difference to above 10ºC. It is also waterproof protection for the buildings that has been widely applied in Europe and America.
Product features and advantages
* coating film is compact, with high adhesive strength
* high sealing performance and penetration resistance, high hiding power
* excellent anti-aging, without peel off, powder or yellowing after long term outdoor use
* excellent heat insulation property
* good acid, alkali resistance and anticorrosion
* excellent waterproof & mildew resistance
* excellent washing-out resistance and pollution resistance
* water based coating, eco friendly, do no harm to environment during application and usage
* one component material, easy operation without ratio mixed, reducing labor costs
Application scopes
Heat insulation protection of building roof, wall, industrial roofing and equipment tanks.
