1. Basic Information
- Definition: Vinyl MQ silicone resin is a co-hydrolyzed product of silane/water glass containing Q units and other monomers. It has a three-dimensional network structure and contains partial vinyl and silanol functional groups.
- Appearance: Common forms include light yellow transparent liquid, colorless transparent liquid, or white powder.
2. Performance Characteristics
- Excellent Heat Resistance: It possesses good heat resistance and can maintain stability at relatively high temperatures.
- Good Film-Forming Property and Adhesion: It can form a uniform film and exhibits strong adhesion to a variety of materials.
- Water Repellency: Its molecular structure endows it with hydrophobicity, with a contact angle with water greater than 90°, resulting in outstanding waterproof performance.
- Modifiability: The vinyl groups, hydrogen-containing groups, and other functional groups introduced into its molecular structure can be used for hydrosilylation modification, thereby endowing the material with more performance attributes and application possibilities.
3. Technical Parameters
Taking the Vinyl Silicone Resin RH-S605-1 from Ningbo Runhe High-Tech Material Technology Co., Ltd. as an example, its key parameters are as follows:
- M/Q Ratio: Approximately 0.8
- Resin Content: 60%
- Viscosity (at 25℃): 11,000 - 15,000 mPa·s
- Vinyl Content: 1.08% - 1.12%
- Volatile Matter: ≤ 1.0%
Note: Parameters may vary slightly among different manufacturers and product models (e.g., molecular weight, hydroxyl content, solid content).
4. Application Fields
- Silicone Rubber Reinforcement: As a reinforcing agent for liquid silicone rubber products, it can enhance the strength of the rubber matrix, improve the mechanical properties of silicone rubber (such as hardness, tensile strength, and tear strength), while maintaining the light transmittance and good fluidity of silicone rubber.
- Pressure-Sensitive Adhesive (PSA) Field: It can be used to adjust the cohesive force, adhesive force, and initial tack of addition-curable silicone PSAs, improving the performance of PSAs. It is an important raw material for the preparation of silicone PSAs.
- Release Agent Field: As a release regulator for addition-curable release agents, its dosage and vinyl content can be controlled to adjust the release performance of the release agent, meeting specific application requirements.
- Waterproof Coatings: Due to its excellent water repellency, it can be used to prepare various waterproof coatings, which are applied for waterproof treatment of building walls, roof tiles, and other materials.
5. Packaging, Storage and Transportation
- Packaging: It is generally packaged in plastic buckets or iron drums, with common specifications including 5kg, 10kg, 20kg, and 25kg.
- Storage: It should be stored in a cool place with sealed packaging. If not fully used after opening, the container must be resealed to avoid contact with moisture in the air. The typical shelf life is 1 year under proper storage conditions.
- Transportation: This product is non-hazardous and can be transported as a general chemical.
