Evonik Dynasylan VTEO is a bifunctional vinyl silane coupling agent that enhances adhesion between inorganic materials (glass, metals, fillers) and organic polymers (thermoplastics, thermosets, elastomers). It serves as a surface modifier and crosslinking agent with versatile reactivity.
Dual Reactivity – Combines hydrolyzable ethoxy groups and vinyl functionality for robust bonding.
Moisture-Induced Crosslinking – Enables wet curing for polymer crosslinking (e.g., polyethylene).
Surface Hydrophobization – Renders fillers and substrates water-repellent and corrosion-resistant.
Water Scavenging – Eliminates trace moisture in sealants and adhesives.
Enhanced Compatibility – Improves dispersion and reduces viscosity in filled polymers.
Wire & Cable Insulation – Crosslinking agent for moisture-curable polyethylene.
Mineral-Filled Composites – Coupling agent for improved mechanical/electrical properties.
Glass & Metal Coatings – Adhesion promoter for anti-scratch and anti-corrosion surfaces.
Sealants & Adhesives – Water scavenger and bonding enhancer.
Acrylic Coatings – Improves adhesion to inorganic substrates.
