In the world of composite materials, the issue of interfacial compatibility between inorganic fillers and silicone matrices often becomes a critical bottleneck limiting material performance. IOTA-2307 mono-terminated trimethoxysilane silicone oil, with its unique molecular structure featuring one reactive end and one pendant end, builds a stable "molecular bridge" for inorganic powders and silicone resins, silicone rubber, and other systems, fundamentally solving the challenges of interfacial bonding and stability.
Reactive end: Active trimethoxysilane forms strong chemical bonds with the surface of inorganic powders
Pendant end: Inert polysiloxane chains extend freely, achieving perfect compatibility with silicone matrices
No migration or precipitation: Chemical bonding ensures silicone oil remains stably at the interface without free migration
Suitable for various inorganic fillers including silica, titanium dioxide, iron oxide, carbon black, and more
Excellent compatibility with silicone resins, silicone rubber, silicone gels, and other silicone systems
Catalyzed reactions can occur at room temperature, offering simple and efficient processing
Uniform product composition, free of cyclic impurities
Available in multiple molecular weight specifications to meet different application needs
Strict quality control ensures batch-to-batch consistency
