Name: Perfluorooctyltrichlorosilane EW-459
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Perfluorooctyltrichlorosilane EW-459

Excellent waterproofness: can make the water drop angle of the treated substrate surface reach more than 118°.
Good stain resistance: can work on a variety of substrates, can prevent edible oil, soy sauce and other stains.
Strong weather resistance: can protect stone for more than 15 years, better than silicone and acrylate protective agents.
Good compatibility: good compatibility with acrylate coatings, a small amount of addition can improve the coating's oil and stain resistance, wear resistance, and increase surface smoothness.
Forming ultra-thin film coating: after treatment, a nano-scale fluorine-containing coating is formed on the surface of the substrate, which does not affect the surface hardness and optical properties of the substrate, and has excellent wear resistance.

Typical Applications Of Perfluorooctyltrichlorosilane EW-459

Coating field: used as a leveling agent and wetting agent in coatings, it can improve the coating's wear resistance, chemical resistance, heat resistance and weather resistance.
Material protection field: used on the surface of glass, ceramics, stone, metal and other materials to make them waterproof, oil-proof, anti-fouling, anti-fingerprint and other properties, such as the protection of building exterior walls, stone furniture, ceramic bathroom, mobile phone screens, optical lenses, etc.
Electronics industry: can be used as a moisture-proof agent for electronic components, and can also be used to prepare high-performance polymers to increase the degradation temperature and insulation performance of polymers, and is used in electronic devices, thermal conductive materials, etc.
Leather industry: added to polyurethane resin or leather finishing agent, it can make leather waterproof, oil-proof, easy to clean, hydrolysis-resistant and other properties, and increase surface smoothness.
