Product Description

1. Low-Viscosity High-Transparency Silicone Curing Crosslinking Precursor

1,1,1,5,5,5-Hexamethyl-3-[(trimethylsilyl)oxy]-3-vinyltrisiloxane is a high-purity branched vinyl-functional trisiloxane with fully methyl-substituted inert skeleton and single-site vinyl active group. The ultra-low viscosity molecular structure provides excellent melt fluidity and uniform dispersion performance, while the single vinyl group achieves precise and controllable crosslinking via platinum-catalyzed hydrosilylation reaction. It effectively avoids excessive crosslinking density and brittle failure defects of multi-vinyl silicone systems, endowing cured silicone materials with high light transmittance, low internal stress and uniform network structure. It is an ideal functional precursor for preparing high-transparency silicone elastomers, optical silicone gels and low-hardness flexible silicone curing systems.

2. High-Efficiency Wetting Leveling & Defect Repairing Modifier for Functional Coatings

Benefiting from the highly symmetric branched trisiloxane topological structure, this monomer possesses ultra-low surface tension and excellent interfacial spreading and wetting capabilities. It can rapidly reduce the surface tension of water-based and solvent-based coating systems, effectively eliminate film-forming defects such as shrinkage cavities, fish eyes, pinholes and edge shrinkage. Different from conventional linear silicone leveling agents, its branched inert siloxane skeleton delivers more stable interfacial activity, without floating oil, precipitation or recoating difficulty. It can significantly improve surface smoothness, gloss uniformity and film-forming compactness, and is widely applicable in high-gloss coatings, optical protective films and high-precision ink systems.

3. Low-Volatility High-Stability Hydrophobic Anti-Fouling Functional Additive

The fully methyl-blocked saturated siloxane skeleton endows the molecule with excellent chemical inertness, low volatility and weather resistance. After uniform doping and film formation on the surface of polymer materials and inorganic substrates, it can construct a dense low-surface-energy protective layer to isolate water, dust and polar pollutants. The branched molecular structure enhances the combination stability between the modifier and the substrate, avoiding migration, precipitation and failure of traditional small-molecule hydrophobic additives. It significantly improves the water resistance, stain resistance and long-term aging resistance of coatings and composite materials, suitable for outdoor weather-resistant coatings and self-cleaning functional film modification.

4. Low-Stress Flexible Organic-Inorganic Hybrid Material Building Block

This vinyl-branched trisiloxane integrates the flexibility of siloxane segments and the inert stability of fully methylated structures. It can be covalently grafted and copolymerized with various resin systems through vinyl active sites to construct ordered organic-inorganic hybrid networks. The unique branched structure effectively optimizes molecular chain stacking, reduces system curing shrinkage and internal stress, and balances the rigidity and flexibility of hybrid materials. It improves the interfacial compatibility between inorganic silicon segments and organic polymers, and enhances the dimensional stability, solvent resistance and mechanical toughness of composite systems, serving as a high-precision customized building block for high-performance hybrid silicone materials.
