Evonik Dynasylan OCTMO Fluorinated Silane Coupling Agent

Evonik Dynasylan OCTMO is a specialized fluorinated silane coupling agent featuring both hydrolyzable inorganic ethoxysilane groups and a fluorinated alkyl chain. This bifunctional design enables exceptional surface modification capabilities, creating ultra-low surface energy coatings with superior hydrophobic and oleophobic properties. The compound forms nanometer-thick, crosslinked networks that provide chemically and mechanically stable surface treatments through covalent bonding with hydroxyl-containing substrates.

Features Of Evonik Dynasylan OCTMO Fluorinated Silane Coupling Agent

  1. Dual Functionality - Combines hydrolyzable ethoxysilane groups with fluorinated alkyl chain

  2. Ultra-Low Surface Energy - Creates superior hydrophobic and oleophobic surfaces

  3. Nanoscale Coating - Forms stable, crosslinked networks only nanometers thick

  4. Covalent Bonding - Establishes permanent chemical bonds with hydroxylated substrates

  5. Broad Solubility - Compatible with ethanol, hexane, xylene, acetone and ethyl acetate

Typical Applications Of Evonik Dynasylan OCTMO Fluorinated Silane Coupling Agent

  1. Automotive Glass - Water-repellent coatings for windshields and windows

  2. Architectural Glass - Easy-clean, anti-UV coatings for building glazing

  3. Surface Protection - Durable hydrophobic treatments for ceramics and minerals

  4. Fluoropolymer Adhesion - Bonding promoter for PTFE and fluorosilicones

  5. Specialty Coatings - Nano-coatings for optical and electronic applications
