Product introduction ：
Silicone water repellent 2# isa nonflammable, water soluble sodium methyl siliconate solution designed toimpart water repellency to a widevariety of surfaces. Supplied at a concentration of 30 percent solids in water, Silicone water repellent 2# is usually diluted to a concentration of 3 percent before being applied. The final concentrationdepends on the application. The siliconate reacts with moisture and carbon dioxide in the air to form aninsoluble water-resistant resin within 24 hours
Properties:
