General Vinyl Silicone Resin
Silico® General Vinyl Silicone Resin is a high-purity organosilicon polymer with reactive vinyl groups on a flexible siloxane chain. Unlike MQ resins, it offers excellent compatibility, flexibility, and curing performance for electronics, adhesives, and UV/thermal-curable coatings.
Product Overview
Typical Specifications (Silico® Grade S-V105)
| Property | Typical Value |

| Viscosity (25 °C) | 800–1000 mPa·s |
| Vinyl Content | 1.3–1.4 wt% |
| Volatile Content | ≤ 1.0 wt% |
| Solubility | Compatible with toluene, xylene, vinyl fluids |
| Structure Type | Non-MQ (linear or branched siloxane) |
Key Features & Benefits
Versatile Curing Options: Supports thermal, UV, or platinum-catalyzed addition (hydrosilylation)
Low Volatility: Ensures bubble-free curing and high yield in precision molding
Excellent Electrical Insulation: Ideal for high-voltage or high-temperature electronics
High Transparency: Suitable for optical-grade formulations like LED potting
Good Film-Forming Ability: Provides flexibility, durability, and moisture protection
Compatible with RTV, HTV & LSR Systems: Enhances bonding, hardness, and crosslinking in silicone rubbers
Application Fields
| Application Segment | Recommended Use |
|---|---|
| Electronic Encapsulation | Potting of PCBs, LEDs, and power modules |
| High-Temp Adhesives | Enhances thermal resistance and bonding |
| Silicone Rubber Compounding | Increases crosslink density in RTV/HTV |
| UV-Curable Coatings | Enables fast curing with excellent durability |
| Anti-Stick & Release Films | Used in mold release and surface protection |
