SIO-729 Solid Organic Silicone Resin

SiO-729 High-Temperature Resistant Phenyl Silicone Resin is a solid organic silicone resin designed for use in powder and solvent-based coatings. This ladder-like phenyl silicone resin, featuring a C6H5SiO3/2 structure, is synthesized using high-purity trifunctional phenyl alkoxy silane through a specialized hydrolytic polymerization process. Its unique ladder structure provides excellent film-forming capabilities and superior resistance to high temperatures.

SiO-729 is widely applied in industries such as plastics, rubber, and coatings. It offers good compatibility with other organic resins, making it versatile for use either as a standalone resin or in combination with other resins. Additionally, it is a solvent-free solid silicone resin, ideal for applications requiring high thermal stability and robust performance in demanding environments.
