Technical Specifications

Main Application Directions

Pure Silicone Resin Synthesis

• Serves as a basic intermediate for preparing high-purity methyl/phenyl silicone resins through polycondensation

• Suitable for high-temperature coatings, insulating coatings, and electronic encapsulation materials

Alkyd Modified Silicone Resins

• Copolymerizes with alkyd resins to enhance coating weather resistance, gloss, and color retention

• Used for long-term protective coatings on outdoor steel structures, bridges, and storage tanks

Acrylic Modified Silicone Resins

• Introduces silicone segments to improve the stain resistance and heat resistance of acrylic resins

• Suitable for architectural exterior wall coatings, waterborne industrial paints, and leather finishing agents

Epoxy Modified Silicone Resins

• Combines the high adhesion of epoxy with the weather and heat resistance of silicones

• Used in heavy-duty anti-corrosion coatings, floor coatings, and composite material matrices

Polymerization and Usage Recommendations

Polymerization Process

• Can be copolymerized with various modified resins through bulk or solution polymerization

• Recommended polymerization temperature: 140–180°C, with catalysts and reaction time adjusted based on the system

Formulation Tips
