Technical Data

Product Description

1H,1H,2H,2H-Perfluorooctyltrichlorosilane (CAS 78560-45-9, C₈H₄Cl₃F₁₃Si, MW 481.54) is a colorless liquid with density 1.638 g/mL (25℃), boiling point 192℃, and refractive index 1.352. As a fluorosilane coupling agent, its molecular structure combines low surface energy of fluorine and film-forming property of silicon, forming a nanometer-thin film on substrates for excellent water/oil repellency and weatherability.

Key Properties
1. Superhydrophobic & Oleophobic：Water contact angle ≥118°, oil contact angle ≥90°, resisting cooking oil and soy sauce stains.
2. Long-Term Weatherability：15+ years protection for stone materials, outperforming silicone protectants (5-8 years).
3. Nanoscale Film Formation：Coating thickness <100nm, negligible impact on substrate transparency (<1% light loss) and hardness.
4. Excellent Compatibility：Compatible with acrylic coatings; 1-3% addition increases abrasion resistance to 5000+ cycles (vs 2000 cycles untreated).
5. Chemical Resistance：Withstands strong acids (pH 1), bases (pH 14), and organic solvents (acetone, toluene).

1. Coatings: used as a leveling agent and wetting agent in coatings to improve the wear resistance, chemical resistance, heat resistance and weather resistance of coatings.

2. Material protection: used on the surfaces of various materials such as glass, ceramics, stone, metal, etc., 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.

3. 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.

4. 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
