Evonik Dynasylan PTMO Silane Coupling Agent

Evonik Dynasylan PTMO is a trifunctional alkyl silane specifically engineered as a key precursor for sol-gel applications. Its unique propyl group provides organic compatibility while the hydrolyzable methoxy groups enable the formation of stable siloxane networks through controlled condensation reactions. This versatile silane demonstrates faster hydrolysis kinetics compared to ethoxy analogs and serves as a fundamental building block for creating hybrid organic-inorganic materials with tailored properties.

Features Of Evonik Dynasylan PTMO Silane Coupling Agent

  1. Trifunctional Reactivity - Three hydrolyzable methoxy groups enable high crosslinking density

  2. Controlled Hydrolysis - Faster reaction kinetics than ethoxy-based silanes

  3. Organic Compatibility - Propyl group enhances compatibility with organic matrices

  4. Network Formation - Facilitates creation of stable siloxane networks

  5. Catalyst Compatibility - Works with both acid and base catalysis systems

Typical Applications Of Evonik Dynasylan PTMO Silane Coupling Agent

  1. Hybrid Coatings - Base component for scratch-resistant organic-inorganic coatings

  2. Surface Modification - Precursor for functionalizing inorganic nanoparticles

  3. Composite Materials - Building block for tailored organic-inorganic composites

  4. Electronic Encapsulation - Protective coatings for electronic components

  5. Specialty Polymers - Modifier for enhancing polymer properties through hybridization
