Evonik Dynasylan SIVO 214 is a specialized multi-amino functional ethoxysilane featuring both primary and secondary amino groups. This unique molecular structure enables superior interfacial bonding between inorganic materials and organic polymers through enhanced crosslinking capabilities.
Self-Catalyzing Hydrolysis - Automatically activates upon moisture exposure without additional catalysts
Dual Reactivity - Combines amino functionality with hydrolyzable methoxy groups
Enhanced Stability - Hydrolyzed form remains stable for over 30 days at pH 11-12
Broad Polymer Compatibility - Effective with epoxies, polyurethanes, acrylics and various thermoplastics
Processing Advantages - Improves filler dispersion and reduces system viscosity
Fiberglass Reinforcements - Sizing agent for glass fiber and mineral wool composites
Metal Primers - Surface pretreatment for enhanced corrosion resistance and adhesion
Mineral-filled Composites - Coupling agent for silicate-filled polymer systems
Insulation Materials - Additive for phenolic resin binders in mineral wool insulation
Coating Formulations - Adhesion promoter for protective coatings and surface treatments
