Vinyl MQ silicone resin dispersion(SF-102 series) is a fluid suspension of vinyl-functional MQ silicone resin (a type of silicone polymer) in a liquid medium, often a vinyl silicone oil, designed for enhanced compatibility and easier use as a reinforcing agent, tackifier, or additive in various silicone products like silicone rubber, coatings, and adhesives. This dispersion provides heat resistance, transparency, and mechanical strength to final products through cross-linking reactions.
MQ Resin: A silicone resin built from "M" (monofunctional) and "Q" (tetrafunctional) siloxane units, providing a stable, high-temperature skeleton.
Vinyl Functionality: The "vinyl" groups on the resin allow it to react and bond with other components (like -SiH groups in silicone rubber) through hydrosilylation reactions.
Dispersion: The resin is suspended in a liquid carrier, often a vinyl-functional silicone oil, to create a low-VOC, easily formable liquid that mixes well with other materials.
Key Applications and Benefits:
Adhesives:
Pressure-Sensitive Adhesives: Improves cohesive strength and allows for adjustment of peel force.
Mold Adhesives: Creates high-transparency, high-elongation mold compounds.
Silicone Rubber:
Reinforcement: Acts as a reinforcing filler, resulting in colorless, transparent silicone rubber with high mechanical strength.
Liquid Silicone Rubber (LSR): Used as a reinforcing material for LSR systems.
Electronics & Optoelectronics:
LED Encapsulation: Serves as a base material and reinforcing agent for adhesives used in encapsulating LEDs.
Potting & Sealing: Provides reinforcement and protection for electronic components.
Coatings:
Waterproof Coatings: Enhances the waterproof properties of automotive and household items.
High-Temperature Coatings: Forms protective films for insulation and sealing applications, especially in H-class motors.
Release Agents:
Mold Release: Improves mold release properties and helps maintain smooth surfaces on molded parts.
Cosmetics:
Lipsticks: Imparts non-transfer properties, enhances color saturation, and provides a smooth application.
Mascaras/Eyeliners: Creates fast-forming films that are smudge-proof and long-lasting.
