Other application features
(1) After fumed silica is surface-treated with methyl acrylsilane, it can be added to the polyurethane coating to play a role in friction resistance.
(2) Fumed silica can also improve the weather resistance and scratch resistance of the coating, and improve the bonding strength between the coating and the substrate.
(3) Fumed silica has strong ultraviolet absorption and infrared light reflection characteristics, and it can improve the anti-aging performance of coatings when added to coatings.
