Silico® V411 Vinyl Silicone Oil (Branched Type)
Silico® -V411 (CAS 63148-57-2) is a branched methyl vinyl silicone oil with vinyl groups in the molecular chain. It offers good reactivity for addition and radical reactions, and improved compatibility with some organic materials. Vinyl content and molecular weight can be independently adjusted.
Product Features
Silico® -V411 (CAS 63148-57-2) is a methyl vinyl silicone oil with a branched structure, featuring vinyl groups embedded within the molecular chain. Its chemical structure is as follows:
(CH₃)₃SiO[(CH₃)₂SiO]ₘ[(CH₂=CH)(CH₃)SiO]ₙSi(CH₃)₃
The molecular weight of DY-V411 can be customized according to user requirements. Unlike linear vinyl silicone oils, its vinyl content and molecular weight can be independently adjusted.
In addition to the typical properties of methyl silicone oils—such as smoothness, softness, gloss, thermal stability, and weather resistance—Silico® -V411 offers the following enhanced characteristics:
Vinyl groups within the molecular chain provide high reactivity, enabling participation in various chemical reactions such as addition and free radical reactions.
Due to the presence of vinyl groups, Silico® -V411 shows improved compatibility with certain organic materials compared to standard methyl silicone oils.
This makes DY-V411 an ideal reactive intermediate for high-performance applications in coatings, sealants, and advanced silicone formulations.
Technical Specifications
| Grade | Viscosity (25°C, cP) | Vinyl Content (mol/100g) |
|---|---|---|
| V411-1000 | 1000 ± 50 | 0.010–0.012 |
| V411-5800 | 5800 ± 200 | 0.00743–0.00905 |
| V411-10000 | 10000 ± 500 | 0.00716–0.00878 |
Applications
Used as a hardening agent and pre-curing diluent in high-viscosity silicone rubbers (e.g., 110-2 grade).
Acts as a modifier for organic resins such as acrylic and vinyl acetate resins.
Suitable for producing high-temperature vulcanized (HTV) silicone rubber, RTV silicone rubber, and silicone gels.
Also applicable in other advanced and developing areas.
Usage Guidelines
As a diluent: Add 10–20%
As a modifier: Add 5–10%
As a silicone rubber base: Add 50–100%
Mix directly or use high-speed or intensive agitation equipment for uniform dispersion.
Precautions
Silico®-V411 (CAS 63148-57-2) is chemically active. Avoid contamination, especially with catalysts, during storage and use. Verify material compatibility to prevent unwanted reactions.
