Product Description

1. Low-Viscosity & High-Transparency Silicone Polymer Precursor

As a symmetric low-tension five-membered cyclic oxadisilane, this monomer features ultra-low viscosity, high structural regularity and excellent environmental stability. It can undergo controlled ring-opening polymerization to synthesize high-transparency, low-shrinkage and low-residual-stress silicone polymers. Without volatile small molecule by-products during curing, it effectively eliminates coating pores and shrinkage defects, and is widely used in the preparation of high-grade transparent silicone resins, optical protective materials and low-VOC environmentally friendly silicone coatings.

2. Low-Surface-Energy Hydrophobic & Anti-Fouling Modifier

The fully methyl-substituted closed-loop siloxane skeleton provides extremely low surface energy and excellent water repellency. Different from traditional hydrolyzable silane modifiers, it achieves long-term stable hydrophobic modification through physical doping and structural embedding without migration, precipitation or failure. It significantly improves the water resistance, stain resistance and weather durability of polymer materials, and is suitable for long-term anti-fouling and water-repellent modification of outdoor coatings and polymer films.

3. Low-Dielectric & High-Insulation Electronic Silicone Intermediate

The non-polar fully saturated silicon-oxygen-carbon closed-loop structure endows the polymerized material with low dielectric constant, low dielectric loss and excellent electrical insulation performance. The compact and defect-free molecular network effectively reduces polarization loss and improves the high-temperature aging resistance and dimensional stability of electronic silicone materials. It is an important precursor for the preparation of high-performance electronic packaging silicone materials and insulating coatings.

4. High-Stability Organic-Inorganic Hybrid Synthesis Building Block

Benefiting from its ultra-high stability, wide compatibility and controllable polymerization characteristics, this cyclic silane monomer can be used as a high-purity structural building block for advanced organic-inorganic hybrid materials. It balances the flexibility of organic alkyl segments and the weather resistance of inorganic siloxane segments, effectively improving the structural compactness, mechanical stability and anti-aging performance of hybrid composite systems.
