2. Performance and Applications
• It can improve the weather resistance, heat resistance and flexibility of organic resins.
• It can be used as a structural intermediate on organic polymers, typically reacted with polyesters or alkyds and acrylic acid to form a copolymer, this copolymer are generally used in coatings, electrical appliance and high-temperature finishes.
• Blended with other silicone resins to reduce solvent loading requirements in high temperature coating formulations.
