Product Description

1. High-Temperature Resistant & High-Transparency Silicone Rubber Crosslinking Monomer

This multi-functional hybrid trisiloxane possesses multiple vinyl active groups and a rigid phenyl side chain on the single molecular skeleton. The symmetric multi-vinyl structure provides high crosslinking density and uniform curing sites for platinum-catalyzed hydrosilylation reactions, enabling efficient and rapid curing of silicone rubber systems. The introduced phenyl functional segment effectively suppresses molecular chain rotation and high-temperature thermal degradation, significantly improving the high-temperature thermal stability, thermal oxidation resistance and structural rigidity of cured silicone materials. Different from ordinary full-methyl vinyl siloxane monomers, it solves the defects of low hardness, poor high-temperature creep resistance and easy yellowing of conventional silicone rubber, and is widely used in the preparation of high-temperature resistant transparent silicone elastomers and high-strength silicone rubber products.

2. Low-Dielectric & Low-Loss Electronic Silicone Encapsulation Precursor

Benefiting from the composite structural advantages of flexible siloxane main chain and rigid phenyl branched chain, this functional trisiloxane can effectively regulate the molecular stacking density and polarization degree of electronic silicone systems. The non-polar saturated siloxane skeleton and uniformly distributed vinyl groups reduce interfacial polarization and dielectric hysteresis loss under alternating electric fields, endowing the cured material with low dielectric constant and ultra-low dielectric loss characteristics. Meanwhile, the phenyl structure improves the high-temperature insulation stability and breakdown field strength of electronic materials, avoiding thermal aging and electrical performance attenuation of traditional electronic silicone gels. It is an ideal functional precursor for high-performance electronic potting adhesives, insulating coatings and semiconductor protective encapsulation materials.

3. Weather-Resistant & Anti-Yellowing Functional Coating Modifier

The integrated phenyl-vinyl composite structure enables the trisiloxane monomer to have excellent UV resistance, radiation resistance and thermal aging resistance. The rigid phenyl group can effectively absorb and shield ultraviolet energy, inhibit molecular chain photodegradation and free radical aging, while the multi-vinyl crosslinking system builds a dense and defect-free three-dimensional crosslinked network. It significantly improves the surface hardness, scratch resistance and long-term weather durability of silicone coatings. Compared with pure alkyl silicone modifiers, it eliminates the shortcomings of poor UV resistance and easy powdering of outdoor coatings, and is suitable for high-grade outdoor weather-resistant coatings, optical transparent protective coatings and long-term anti-aging functional film materials.

4. Organic-Inorganic Hybrid Material Customized Building Block

As a high-precision asymmetric functional polysiloxane monomer, it combines the flexibility of alkyl siloxane segments, the rigidity and weather resistance of phenyl groups, and the crosslinking activity of multi-vinyl groups. It can be copolymerized and grafted with various resin systems to construct ordered organic-inorganic hybrid structures. The multi-site reactive characteristic ensures high grafting efficiency and uniform structural distribution in composite systems, effectively balancing the flexibility and mechanical strength of hybrid materials. It optimizes the interfacial compatibility between inorganic silicon segments and organic polymer matrices, improves the compactness, solvent resistance and dimensional stability of composite materials, and is widely used in the customized synthesis of high-performance hybrid silicone resins and functional composite materials.
