Description

(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl)Tris(1-Methylethoxy)Silane is a highly specialized fluorinated organosilane coupling agent, distinguished by its long perfluorinated alkyl chain. This compound is engineered to impart exceptional hydrophobic, oleophobic, and low surface energy properties to treated surfaces, making it a critical performance additive. It is primarily utilized in advanced material science and high-tech manufacturing sectors where durable, non-stick, and chemically resistant coatings are required.

Application

• Surface Modification Agent: Used to create durable, water- and oil-repellent (omniphobic) coatings on glass, ceramics, metals, and polymers.
• Textile & Leather Treatment: Imparts permanent stain and water resistance to high-performance fabrics, outdoor gear, and luxury leather goods.
• Electronics & Microelectronics: Applied as a dielectric layer or moisture barrier in semiconductor devices and printed circuit boards (PCBs).
• Optical Coatings: Used to create anti-fog, anti-reflective, and easy-to-clean coatings on lenses, displays, and optical sensors.
• Stone & Masonry Protection: Provides long-lasting protection against water, oil, and graffiti for architectural stone, concrete, and marble.
• Adhesive & Sealant Additive: Enhances the moisture resistance and weatherability of silicone-based adhesives, sealants, and elastomers.
• Biomedical Device Coating: Used to create biocompatible, low-friction, and anti-fouling surfaces on medical implants and instruments.

Quality Control

Our production of (3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl)Tris(1-Methylethoxy)Silane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, FT-IR, and GC/HPLC analysis, to ensure chemical identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the container must be kept tightly sealed in a cool, dry place. Recommended storage temperature is between 2°C and 8°C under an inert atmosphere (e.g., nitrogen or argon) to maximize shelf-life stability. Allow the container to reach room temperature before opening to prevent moisture condensation.
