Description

Adipic Acid, Propylene Glycol, Isophthalic Acid, Neopentyl Glycol, Maleic Anhydride Polymer CAS NO 67599-39-7 is a specialized polyester resin intermediate or prepolymer, synthesized from a precise blend of diacids and diols. This compound is engineered to deliver exceptional thermal stability, chemical resistance, and controlled reactivity, making it a critical component for high-performance polymer formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as producers of unsaturated polyester resins (UPR) for composites and gel coats.

Application

• Unsaturated Polyester Resins (UPR): A key raw material for formulating high-grade UPRs used in fiberglass-reinforced plastics (FRP) for marine, automotive, and construction applications.
• High-Performance Coatings: Serves as a resin backbone for industrial and protective coatings requiring excellent durability, gloss retention, and corrosion resistance.
• Gel Coats & Composites: Used in the production of smooth, glossy, and weather-resistant gel coat surfaces for boats, sanitary ware, and architectural panels.
• Adhesives & Sealants: Imparts strong adhesion and flexibility in structural adhesives and specialty sealants.
• Alkyd Resins Modifications: Employed to modify alkyd resins, enhancing drying time, hardness, and chemical resistance in surface coatings.
• Specialty Elastomers: Acts as a precursor in the synthesis of polyurethane and other elastomeric materials with tailored properties.
