Typical Properties

Product Introduction:

Diethoxy(methyl)(3,3,3-trifluoropropyl)silane is a specialized organosilane compound. It features a trifluoropropyl group (CF3CH2CH2-) and a methyl group attached to a silicon atom, along with two ethoxy groups (-OEt). It typically appears as a colorless to pale yellow clear liquid.

This compound is highly valuable for surface modification and as a coupling agent due to its unique combination of functionalities: the trifluoropropyl tail imparts hydrophobicity and chemical resistance, the methyl group provides steric hindrance and influences film properties, while the two ethoxy groups readily hydrolyze and condense to form siloxane bonds, allowing for strong adhesion to various inorganic substrates.

Main Uses:

1. Surface Modification and Hydrophobic Coatings: It is extensively used to create hydrophobic, oleophobic, and chemically resistant coatings on a wide range of surfaces, including glass, ceramics, metals, and textiles. These coatings improve water repellency, stain resistance, and durability, particularly in harsh environments.

2. Adhesion Promoter and Coupling Agent: It acts as an effective adhesion promoter between organic polymers and inorganic substrates. By forming a stable interface, it improves the bonding strength and durability of fluorinated composites, coatings, and sealants, especially where adhesion to a fluorine-containing polymer is desired.

3. Sol-Gel Chemistry: In sol-gel processes, this silane is used as a precursor for the formation of fluorinated hybrid inorganic-organic materials. These materials exhibit enhanced thermal stability, hydrophobicity, and specific mechanical properties due to the controlled incorporation of the fluorinated alkyl chain.

4. Silicone Polymer Synthesis: It can be used as a monomer in the synthesis of specialized silicone polymers (polysiloxanes) that contain trifluoropropyl groups. These fluorosilicone polymers are known for their excellent resistance to fuels, oils, and extreme temperatures.

5. Electronic and Optical Applications: Modified surfaces or materials containing this silane can find application in electronics for insulation or passivation, and in optics for anti-reflective or anti-smudge coatings.
