Evonik Dynasylan 1124 is a unique secondary amino silane featuring dual symmetric silicon atoms, specifically engineered to create highly crosslinked networks between inorganic substrates and organic polymers through its exceptional bonding capabilities.
Dual Silicon Architecture - Two symmetric silicon atoms enable superior crosslinking density
Secondary Amino Functionality - Provides controlled reactivity and enhanced alkaline resistance
High Crosslinking Capacity - Six hydrolyzable methoxy groups form dense network structures
Acid-Catalyzed Hydrolysis - Optimized performance at pH 2-3 with formic/acetic acid
Broad Polymer Compatibility - Effective with epoxy, polyurethane, phenolic and various resins
Metal Primers - Corrosion-resistant pretreatment for metal surfaces
Adhesive Formulations - Crosslinking enhancer in silane-terminated polyurethane prepolymers
Foundry Resins - Additive for phenolic, furan and melamine casting resins
Composite Materials - Coupling agent for mineral-filled polymer compounds
Coating Systems - Adhesion promoter for paints and protective coatings
