BST-509 Water/Oil Dual-Repellent Easy-Clean Nano Coating
BST-509 is a self-crosslinking nano pure silicone resin. It is additive-free, non-migrating, and provides long-lasting anti-graffiti performance. It can be widely used on wood, thermoplastics, stone, metal, glass, or other coated surfaces. It exhibits good adhesion to various substrates, with hydrophobic, oleophobic, anti-mold and antibacterial, and anti-graffiti properties, and can pass FDA certification. With outstanding features, after wiping, the gloss and fullness of the substrate are significantly improved. It features high hardness, high wear resistance, anti-staining, anti-aging, yellowing resistance, pollution resistance, and solvent resistance. It is resistant to boiling water and high temperature up to 300°C, and resistant to corrosion from polar organic solvents (such as alcohol, PMA, and lacquer thinner), white vinegar, red wine, cola, and other media.
☑ Fluorine-free formula, the coating can reach food-grade level and can pass U.S. FDA certification.
☑ Nano-scale material, ultra-thin coating, large equivalent coverage area, convenient application, and fast drying.
☑ Adjustable long-term high-temperature resistance up to 300°C; hydrophobic, oleophobic, and easy-clean performance does not degrade.
☑ Good adhesion on the vast majority of substrates.
