Description

Silane, Trimethyl(Tridecafluorohexyl)- CAS NO 135841-49-5 is a specialized fluorinated organosilicon compound, characterized by its unique combination of a silane head group and a long perfluoroalkyl chain. This structure is critical for imparting exceptional surface energy reduction, chemical resistance, and hydrophobic/oleophobic properties to treated substrates. It is an essential intermediate and surface modification agent for manufacturers in high-tech industries requiring advanced material performance. Key users include producers of specialty coatings, electronics, and high-performance textiles.

Application

• Surface Modification Agent: Imparts durable water, oil, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Coupling Agent for Composites: Enhances adhesion between inorganic fillers (like glass or minerals) and fluoropolymer matrices in advanced composites.
• Electronics & Semiconductor Industry: Used as a precursor for low-surface-energy coatings and as a modifying agent in photoresists or dielectric materials.
• Specialty Coatings & Inks: Formulated into coatings for optical devices, anti-graffiti surfaces, and release layers to provide chemical resistance and easy-clean properties.
• Stone & Masonry Protection: Serves as a key ingredient in sealants and treatments to protect building materials from moisture, weathering, and biological growth.
• Intermediate for Synthesis: Used in the production of more complex fluorinated silanes, surfactants, and specialty polymers.
