Evonik Dynasylan 1122 is a bifunctional aminosilane coupling agent specifically designed to enhance interfacial adhesion between inorganic substrates and organic polymers. Its unique molecular structure features six hydrolyzable groups, making it particularly effective for creating highly crosslinked networks in composite materials.
High Purity - 28.5% silica content with consistent quality
Tetrafunctional - Four ethoxy groups enable dense crosslinking
Controlled Reactivity - Tunable hydrolysis rates with acid/base catalysts
Excellent Stability - Forms durable Si-O-Si networks upon curing
Silicone Rubber - Crosslinking agent for high-temperature elastomers
Sealants & Adhesives - Moisture scavenger in one-component systems
Surface Coatings - Precursor for scratch-resistant hybrid coatings
Composite Materials - Binder for inorganic-organic hybrid systems
Nanomaterial Synthesis - Silica source for sol-gel processes
