Description

4,7-Methanoisobenzofuran-1,3-Dione, 4,5,6,7,8,8-Hexachloro-3A,4,7,7A-Tetrahydro-, Polymer With 2,2-Dimethyl-1,3-Propanediol, 2,5-Furandione And 1,2-Propanediol is a specialized chlorinated polyester resin intermediate, known for its excellent chemical resistance and thermal stability. This compound is critical for formulators seeking to enhance the durability and flame-retardant properties of high-performance coatings and composite materials. It is primarily utilized by manufacturers in the protective coatings, electrical insulation, and advanced polymer industries.

Application

• Flame-Retardant Coatings: A key resin component in intumescent and protective paints for steel, wood, and plastics.
• High-Performance Inks: Used in specialty printing inks requiring chemical and abrasion resistance.
• Electrical Encapsulants: Provides insulation and protection in potting compounds and sealants for electronic components.
• Adhesive Formulations: Imparts strength and environmental resistance in structural and industrial adhesives.
• Composite Materials: Serves as a cross-linking agent or modifier in fiber-reinforced plastics (FRP) and laminates.
• Corrosion-Resistant Linings: Used in tank linings and industrial floor coatings where chemical exposure is high.
