Phenyltris (trimethylsiloxy) silane (HC-5101)

1,3-Dimethyl-1,1,3,3-tetraphenyldisiloxane is a high-phenyl-content organosilicon intermediate. Featuring a unique symmetrical molecular structure with “dual methyl and tetraphenyl” groups, it combines the high heat resistance, radiation resistance, and excellent optical properties of phenylsiloxanes with the good compatibility of methylsiloxanes. It serves as a key raw material for preparing high-performance phenyl silicone rubber, silicone resins, optical materials, and high-temperature-resistant coatings, as well as a chain-terminating agent for phenyl silicone oils. The product is widely suitable for material upgrade requirements in precision fields such as aerospace, electronic information, and high-end manufacturing.

Methylphenyl cyclosiloxane mixture is a key intermediate for the preparation of high-performance polysiloxane materials, as well as a versatile organosilicon compound. It refers to cyclic siloxanes where each silicon atom is substituted with both methyl and phenyl groups simultaneously. High-purity methylphenyl cyclosiloxane free of trifunctional impurities serves as one of the raw materials for manufacturing high-temperature vulcanized (HTV) methylphenyl silicone rubber. In addition, methylphenyl cyclosiloxane features excellent physiological inertness, surface activity, aging resistance, UV radiation resistance and light transmittance, with the characteristics of non-toxicity and odorlessness. It is widely used as a primary and auxiliary agent in cosmetics, and can also be applied in the pharmaceutical and medical and health industries. Leveraging its unique phenyl-modified structure, which integrates the stability of methylsiloxane and the special functionalities of phenyl groups, it provides core material support for high-end electronics, aerospace, medical protection and other fields, and is an indispensable basic organosilicon raw material for high-end manufacturing.

Triphenylsilanol is a specialty organosilicon compound that combines ultimate structural stability with high-efficiency interfacial reactivity. In its molecular structure, the triphenyl groups endow materials with outstanding thermal resistance, radiation resistance, yellowing resistance and mechanical toughness through the steric hindrance effect. The hydroxyl groups (-OH) possess direct condensation reactivity; without the intermediate hydrolysis step, they can rapidly form stable chemical bonds with silanols, hydroxyl resins and hydroxyl groups on filler surfaces. As a core functional additive for high-end silicone resin crosslinking, specialty organosilicon modification and precision filler functionalization, the product leverages the dual advantages of stable performance without attenuation and high reaction efficiency. It is widely used in fields with stringent requirements for material performance and processing precision, such as aerospace, high-end electronic manufacturing, medical devices, special coatings and precision composites, providing comprehensive performance assurance for end products. Its additional applications are as follows: Surfactant: Triphenylsilanol can serve as a surfactant with excellent surface tension reduction capability, and is widely used in various chemical and industrial applications. Wetting Agent: It can also be used to improve the wetting properties of certain materials, such as coatings, dyes and paints. Papermaking Additive: It acts as a papermaking additive to enhance the wet strength and wettability of paper. Sealing Wax Agent: In electronic assembly and packaging processes, triphenylsilanol can be used as a sealing wax agent to improve the adhesion and heat resistance of packaging materials.
