Shanghai’s Lujiazui skyscrapers are adopting silicone resin self-cleaning coatings in a façade renewal project. The coating forms nano-scale hydrophobic layers via siloxane bonding, repelling dust and acid rain—rainwater alone restores cleanliness. With 10+ years of corrosion resistance, China Academy of Building Research confirms its UV durability triples that of traditional fluorocarbon paints, reducing maintenance costs by 40%. Over 20 cities including Beijing and Shenzhen now include it in urban renewal recommendation lists. Products-IOTA
