Description

(Heptadecaflroro-1,1,2,2-Tetrahydrodecyl)Tris(Dimethylamino)Silane is a highly fluorinated organosilicon compound featuring a reactive aminosilane head group. This specialized chemical is engineered to impart exceptional surface properties, including oleophobicity, hydrophobicity, and chemical resistance. It is a critical precursor for formulators and manufacturers in advanced materials sectors, particularly for creating durable, low-surface-energy coatings and modifying inorganic substrates. Industries such as electronics, specialty textiles, and high-performance composites rely on this silane for its unique ability to provide long-lasting functionalization.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, and metals for anti-fingerprint, anti-stain, and easy-clean applications.
• Electronics Manufacturing: Serves as a key ingredient in formulating protective coatings for printed circuit boards (PCBs), semiconductors, and display screens to repel moisture and contaminants.
• Textile Finishing: Imparts durable water and oil repellency (DWR) to technical fabrics, outdoor gear, and medical textiles.
• Composite Materials: Functions as a coupling agent to improve the adhesion and compatibility between fluorinated polymers and inorganic fillers or reinforcements.
• Stone and Masonry Protection: Applied as a treatment to provide long-lasting protection against water, oil, and graffiti on natural stone, concrete, and brick.
• Release Coatings: Utilized in the formulation of non-stick and easy-release coatings for industrial molds and liners.
