Trimethoxy(3,3,4,4,5,5,6,6,7,7,8,8,8 - tridecafluorooctyl)silane EW-1302

Trimethoxy(3,3,4,4,5,5,6,6,7,7,8,8,8 - tridecafluorooctyl)silane,CAS number is 85857-16-5, molecular formula is C11H13F13O3Si, molecular weight is 468. EW-1302 is a colorless transparent liquid, density ~1.457, refractive index 1.335, boiling point 88℃ (or 263.8℃/760mmHg), flash point >65℃, melting point <0℃. As a fluorosilane coupling agent, its structure combines the low surface energy of fluorine and the bonding ability of silicon. After hydrolysis, it forms a nano protective film with excellent water and oil repellency and weather resistance.


Features Of Trimethoxy(3,3,4,4,5,5,6,6,7,7,8,8,8 - tridecafluorooctyl)silane EW-1302

  1. Low surface free energy: It can make the surface of the object have extremely low surface energy, thus producing excellent water-repellent and oil-repellent properties, making it difficult for water and oil to adhere to the surface.

  2. High chemical stability: It has good chemical corrosion resistance and can resist the erosion of various chemical substances. It is not easy to deteriorate due to chemical reactions.

  3. Good UV resistance and weather resistance: It has good resistance to ultraviolet rays. Under long-term light and different climatic conditions, the performance is stable and not easy to age.

  4. Good heat resistance: It can maintain stable performance under high temperature environment, and it is not easy to decompose or change performance.

Typical Applications Of Trimethoxy(3,3,4,4,5,5,6,6,7,7,8,8,8 - tridecafluorooctyl)silane EW-1302

  1. Surface protection: used for waterproof, anti-fouling, and anti-weathering treatment of cultural relics, masonry, concrete products, ceramics, marble, wood, etc., which can effectively prevent the intrusion of moisture, stains, etc. and extend the service life of the material.

  2. Electronic products: as an anti-fingerprint agent for glass products such as advanced mobile phone screens and camera lenses, it can reduce fingerprint residues while providing waterproof and anti-fouling properties.

  3. Fiber and leather: used in natural fiber (wool, cotton, leather, etc.) products, it can reduce water holding capacity, improve surface water repellency and anti-fouling properties, and make fabrics and leathers have better waterproof, oil-proof and anti-fouling effects.

  4. Other fields: as sol-gel raw materials, fluorosilicone resin synthesis raw materials, pigment surface modification (cosmetics) raw materials, and can also be used as bonding promoters between inorganic materials and fluoropolymers, etc.
