Description

Ethyleneglycol, Polymer With Maleic Anhydride, Phthalic Anhydride And 1,4,5,6,7,7-Hexachlorobicyclo [2.2.1]Hept-5-Ene-2,3-Dicarboxylic Acid is a specialized chlorinated polyester resin, commonly known as a chlorinated alkyd or a flame-retardant polyester. This engineered polymer is valued for its ability to impart durability, chemical resistance, and inherent flame-retardant properties to coatings and composite materials. It is a critical raw material for formulators in industries requiring high-performance, protective surface treatments and specialty polymers.

Application

• Flame-Retardant Coatings: A key resin component in intumescent and non-intumescent fire-protective paints and varnishes for structural steel, wood, and plastics.
• High-Performance Industrial Finishes: Used in corrosion-resistant primers and topcoats for marine, chemical plant, and heavy machinery applications.
• Wire and Cable Insulation: Imparts flame retardancy and thermal stability to insulating enamels and jacketing compounds.
• Adhesives and Sealants: Enhances the chemical resistance and durability of high-strength structural adhesives and specialty sealants.
• Molding Compounds: Serves as a reactive modifier in thermoset molding compounds to improve fire safety ratings (e.g., UL 94).
• Printing Inks: Used in specialty printing inks where chemical and abrasion resistance are paramount.
