Usage & Dosage
This product undergoes high-temperature curing at 200–220℃ for 1 hour to achieve optimal performance.
Important Notes
- Solvent Selection: The dilution solvent must be free of moisture, sulfur compounds, pyridine, and other impurities, as these can affect adhesion, drying time, and overall performance.
- Ventilation & Safety: The production process emits xylene and other flammable, toxic solvents, requiring proper ventilation, strict fire safety measures, and avoidance of ignition sources. Operators must follow labor protection guidelines.
- Clean Processing Equipment: Ensure all processing equipment and containers are clean to prevent contamination from dust, foreign particles, or moisture.

Phenyl Silicone Resin : Guide
Phenyl silicone resin is mainly used as a base resin for heat-resistant and special coatings. It is widely applied in heat-resistant insulating paints, varnishes (including color and magnetic paints), and H-grade electrical insulating materials, offering excellent durability in high-temperature environments.
For best results, use a dilution solvent free of water, pyridine, and sulfur-containing impurities, as these can affect adhesion, drying, and film performance.
During application, keep equipment and containers clean to prevent contamination. As the resin releases flammable and toxic solvents like xylene, ensure good ventilation, fire safety, and proper labor protection.
