ERICW EW-17 Trimethoxy(2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10- Octadecafluorodecyl)Silane

Leveraging advanced thermo-mechanical properties, ERICW EW-17 delivers nanoscale amphiphobic protection (water contact angle ≥118°, oil contact angle ≥85°) through self-assembled fluorosilane technology. Compatible with glass, metals, and fibers at 0.5-2% dosage, it enables durable contamination resistance and anti-reflective performance for electronic displays and architectural glass, complying with RoHS 3.0 standards.

Features Of ERICW EW-17 Trimethoxy(2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10- Octadecafluorodecyl)Silane

  1. Ultra-Low Surface Energy: Surface tension ≤18.5 mN/m, static water contact angle ≥118°, enabling self-cleaning "lotus effect".

  2. Chemical Stability: Resists 5% HCl/NaOH immersion for 168h, stable in acetone/ethanol.

  3. Self-Assembled Film: Forms ≤10 nm dense fluorosilane layer via hydroxyl bonding, adhesion ISO Class 0.

  4. Optical Enhancement: Low refractive index (1.328-1.338) reduces light reflection, transmittance ≥97%.

  5. Eco-Safety: PFOA/PFOS-free, RoHS 3.0 compliant, LD₅₀ >2,000 mg/kg (rat oral)

Typical Applications Of ERICW EW-17 Trimethoxy(2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10- Octadecafluorodecyl)Silane

  1. Electronic Coatings: Anti-fingerprint film for phone screens/camera lenses (80% smudge reduction).

  2. Glass Self-Cleaning: Building facade coatings (>90% dirt removal by rainwater).

  3. Functional Textiles: Triple-resistant finishing for fabrics (50+ wash cycles).

  4. EMI Shielding Materials: Hydrophobic modification for polymer composites (shielding ≥60 dB).

  5. Hydrophobic Proppants: Surface treatment for ceramic/carbon nanotubes in oil extraction.
