Vinyl Terminated Silicone Fluid

Compatibility and Applications of Vinyl Terminated Silicone Fluid with Organic Solvents​

Vinyl Terminated Silicone Fluid (CAS 68083-19-2) is highly compatible with a wide range of organic solvents, making it a versatile material for industrial applications. Its molecular structure, featuring reactive vinyl groups at the terminals of a polydimethylsiloxane backbone, allows it to dissolve efficiently in solvents like toluene, acetone, cyclopentasiloxane, isododecane, and mineral oils. This solubility enables seamless integration into formulations requiring enhanced processing, crosslinking, or modification of polymers.

​Technical Properties and Solubility Performance​

The fluid’s solubility stems from its flexible siloxane chain and customizable viscosity (ranging from 20 to 100,000 mPa.s), which can be tailored to specific solvent systems. Key technical attributes include:

• ​Low Volatile Content​ (<0.3% at 100°C), ensuring minimal evaporation during processing.
• ​Vinyl Content Flexibility​ (0.06–20%), allowing precise control over reactivity in crosslinking reactions.
• ​Thermal Stability​ (flash point >200°C), making it suitable for high-temperature applications.

These properties ensure uniform dispersion in solvent-based formulations, preventing phase separation and enhancing product performance.

​Industry Applications and Solutions​

​1. Coatings and Sealants​

Vinyl Terminated Silicone Fluid acts as a modifier in polyurethane and acrylic coatings, improving weather resistance, UV stability, and toughness. For example, in architectural coatings, it reduces cracking and extends service life. Its solubility in hydrocarbon solvents (e.g., xylene) facilitates easy application as a primer for metal-to-silicone adhesion.

​2. Silicone Rubber Manufacturing​

As a diluent or crosslinking agent, the fluid is dissolved in organic solvents to reduce viscosity before vulcanization. This is critical in producing Liquid Silicone Rubber (LSR) and High-Temperature Vulcanized (HTV) silicone rubber, where it enhances flowability without compromising mechanical strength. Biyuan’s Vinyl Terminated Silicone Fluid, for instance, is optimized for LSR formulations, ensuring bubble-free curing and superior tear resistance.

​3. Cosmetics and Personal Care​

Compatible with cosmetic solvents like cyclopentasiloxane, it is used in shampoos, conditioners, and skincare products to impart gloss and softness. Its low volatile content and biocompatibility meet FDA and LFGB standards for safety.

​4. Electronics and Potting Compounds​

In LED encapsulation and electronic potting, the fluid dissolved in solvents ensures even coverage and enhances dielectric properties. Its reactivity with hydrogen silicone oil via platinum catalysts creates robust, heat-resistant seals.

​Addressing Customer Pain Points​

• ​Process Efficiency: Poor solubility of silicone fluids can lead to clumping or uneven mixing. Biyuan’s tailored viscosity options (e.g., 50–100,000 cSt) ensure rapid dissolution, reducing processing time and energy costs.
• ​Regulatory Compliance: Many industries require materials meeting FDA, LFGB, or ISO standards. Biyuan’s fluids exceed these benchmarks, with heavy metal content ≤10ppm and non-toxic certifications.
• ​Cost Optimization: By enabling lower usage doses (5–10% as additive, 50–100% as base material), the fluid reduces raw material costs while enhancing end-product performance.

​Market Analysis and Standards​

The global demand for Vinyl Terminated Silicone Fluid is driven by industries like automotive (e.g., seals and gaskets), healthcare (medical-grade devices), and construction (waterproof coatings). Compliance with T/FSI018-2019 (China’s silicone industry standard) and ISO certifications ensures reliability. Biyuan’s manufacturing capabilities align with these standards, offering custom formulations for niche applications.
