USi-F10 — 1H,1H,2H,2H-Perfluorodecyltriethoxysilane
Ultra-Hydrophobic & Oleophobic Fluorosilane for Advanced Surface Protection
Also known as: (Heptadecafluoro-1,1,2,2-tetrahydrodecyl)triethoxysilane
CAS No.: 101947-16-4
📄 Product Description
- Chemical Name: 1H,1H,2H,2H-Perfluorodecyltriethoxysilane
- Molecular Formula: C₁₆H₁₉F₁₇O₃Si
- Appearance: Colorless to light yellow liquid
- Key Feature: Combines long-chain perfluoroalkyl (C8F17) with hydrolyzable triethoxysilane group for durable covalent bonding to inorganic surfaces
✅ Delivers exceptional water/oil repellency, anti-fouling, and low surface energy properties
✅ Forms molecularly thin, transparent, and abrasion-resistant coatings(High-resolution chemical structure available upon request)

🌐 Applications
USi-F10 enables next-generation protective coatings across high-tech industries:
🔌 Electronics Protection
- Hydrophobic/oleophobic coating for PCBs, sensors, displays, and connectors
- Prevents corrosion from moisture, sweat, and oils while maintaining electrical performance
🪞 Self-Cleaning & Anti-Reflective Surfaces
- Applied on glass, ceramics, or optical lenses
- Ultra-low refractive index reduces glare and light reflection
- Enables “easy-clean” functionality—dust, water, and oil slide off effortlessly
🧵 Textile & Fiber Treatment
- Imparts durable stain resistance and water/oil repellency to glass fibers, fabrics, and filtration media
- Maintains substrate breathability and texture
💡 Why choose fluorosilanes?
Unlike temporary sprays, USi-F10 forms a covalently bonded monolayer that resists washing, UV, and thermal aging.
🧪 Recommended Usage
- Surface Preparation: Clean substrate thoroughly; activate with mild acid (e.g., acetic acid) or base catalyst if needed.
- Dilution: Typically used at 1–2% concentration in isopropanol or ethanol.
- Application: Dip-coating, spray, or wipe-on methods. Cure at room temperature or mild heat (60–120°C).
- Safety:
- Use in well-ventilated area
- Wear chemical-resistant gloves and protective eyewear
- Refer to SDS before use
📦 Packaging
- 1 kg HDPE bottle
- 5 kg HDPE bottle
- 25 kg pail (plastic)
(All containers are sealed, labeled, and light-protected for stability)
🛡️ Storage & Shelf Life
- Store in a cool, dry, dark place
- Keep container tightly closed to prevent moisture ingress (hydrolysis-sensitive)
- Shelf Life: 12 months from production date in original unopened packaging at ambient temperature
