We are looking for subcontractors for waterproofing work!

Heat-insulating and heat-retaining paint using a special ceramic developed by NASA that does not conduct heat even at 1300℃.

"CoolSarm" is a thermal insulation and heat-resistant paint developed from ceramic technology used in NASA's Space Shuttle. This NASA-developed special ceramic, consisting of four types, forms a layer in the coating that powerfully reflects and dissipates solar energy. It significantly cuts down on heat intrusion from the roof and demonstrates a temperature reduction effect. Since its initial introduction to Japan in 1993, it has been a flagship product, covering an area of 7 million m², and has gained absolute trust in its effectiveness from many companies. 【Features】 ○ Special ceramics developed by NASA ○ Outstanding temperature reduction effect ○ Superior durability of effectiveness ○ High safety ● For more details, please contact us or download the catalog. *This catalog is a digest version.
