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.
Dual Functionality - Combines hydrolyzable ethoxysilane groups with fluorinated alkyl chain
Ultra-Low Surface Energy - Creates superior hydrophobic and oleophobic surfaces
Nanoscale Coating - Forms stable, crosslinked networks only nanometers thick
Covalent Bonding - Establishes permanent chemical bonds with hydroxylated substrates
Broad Solubility - Compatible with ethanol, hexane, xylene, acetone and ethyl acetate
Automotive Glass - Water-repellent coatings for windshields and windows
Architectural Glass - Easy-clean, anti-UV coatings for building glazing
Surface Protection - Durable hydrophobic treatments for ceramics and minerals
Fluoropolymer Adhesion - Bonding promoter for PTFE and fluorosilicones
Specialty Coatings - Nano-coatings for optical and electronic applications
