Evonik Dynasylan 1146 is an oligomeric diamino/alkyl silane copolymer designed as a versatile adhesion promoter. Its unique oligomeric structure provides excellent wettability and chemical bonding to challenging substrates while maintaining low viscosity and minimal VOC emissions.
Dual Functionality - Combines diamino reactivity with alkyl hydrophobicity
Oligomeric Structure - Linear and cyclic siloxanes for enhanced substrate wetting
Low VOC Emission - Minimal odor and reduced environmental impact
Non-Yellowing - Maintains clarity in high-elasticity formulations
Excellent Compatibility - Works with various amino-reactive resins
Hybrid Sealants - Adhesion promoter for MS polymer and silicone-modified polyurethanes
Epoxy Systems - Bonding enhancer for two-component epoxy formulations
RTV Silicones - Adhesion improvement in room-temperature vulcanizing rubbers
Surface Primers - Multi-substrate primer for concrete, aluminum and PVC
Filler Treatment - Surface modification for inorganic fillers in composite systems
