Key Features & Benefits

  • Vinyl Reactivity for Crosslinking
    Vinyl groups provide reactive sites for addition curing (hydrosilylation), enabling strong crosslinked networks in RTV, HTV, and LSR systems.


  • Superior Heat Resistance
    Maintains stability from –60 °C to +300 °C. After full curing, films can withstand temperatures up to 800 °C with excellent integrity.


  • Excellent Transparency & High Refractive Index
    Achieves light transmittance ≥ 98% and refractive index ~1.405–1.41, making it ideal for LED encapsulants, optical coatings, and electronics.


  • Enhanced Film Strength & Durability
    Forms dense, uniform films with high hardness, tear strength, and abrasion resistance.


  • Outstanding Weatherability
    Resistant to UV radiation, oxidation, and humidity, extending the service life of coatings and silicone-based materials.


  • Low VOC & Versatile Compatibility
    Offered as a solvent-free resin or pre-dispersed in toluene, xylene, or PDMS, ensuring easy formulation and compliance with environmental regulations.

Applications of Silico® MQ Resin Dispersion

Silico® Vinyl MQ Silicone Resin is highly versatile and suitable for the following:

  • High-Temperature Coatings
    Used in protective and decorative coatings for metal, glass, and industrial components exposed to high heat.


  • LED Encapsulation & Optical Silicone
    Enhances clarity and thermal stability in LED lenses, potting compounds, and transparent gels.


  • Liquid Silicone Rubber (LSR) Reinforcement
    Improves mechanical strength, elasticity, and transparency in medical and industrial-grade silicone rubbers.


  • Silicone Pressure-Sensitive Adhesives (PSA)
    Enhances tack, cohesion, and temperature resistance in silicone-based PSA formulations.


  • Sealants & Elastomers
    Acts as a structural binder and reinforcement agent in high-performance silicone sealants and elastomeric systems.


  • Mold Release Agents
    Functions as a durable non-stick additive in mold release formulations for rubber and plastics.
