Description

Triethoxy[5,5-Bis(trifluoromethyl)-6,6,7,7,8,8,8-heptafluorooctyl]silane is a highly fluorinated organosilane coupling agent engineered to impart exceptional surface properties. This compound matters for its ability to create durable, low-surface-energy coatings with outstanding oil, water, and chemical repellency. It is primarily needed by manufacturers in the advanced materials, specialty coatings, and electronics industries seeking to develop high-performance, fluorinated surfaces.

Application

• Surface Modification Agent: For creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Fluorinated Silicone Synthesis: As a key monomer in the production of specialty fluorosilicone polymers and resins.
• Adhesion Promotion: To enhance the bonding between fluorinated materials and inorganic substrates in composite manufacturing.
• Electronics & Semiconductor: For low-dielectric-constant (low-k) film deposition and surface passivation to improve device performance and reliability.
• Textile & Leather Treatment: Imparts durable stain, water, and oil resistance to fibers and finished goods.
• Anti-fouling & Anti-icing Coatings: Used in formulations for marine, aerospace, and automotive applications to prevent adhesion of contaminants and ice.

Quality Control

Our production of Triethoxy[5,5-Bis(trifluoromethyl)-6,6,7,7,8,8,8-heptafluorooctyl]silane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and GC, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
