Description

Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer CAS NO 28407-73-0 is a high-performance, synthetic polyester resin known for its excellent durability and chemical resistance. This copolymer is engineered to deliver superior thermal stability and mechanical properties, making it a critical component in demanding industrial applications. It is primarily sought after by manufacturers in the coatings, plastics, and specialty adhesives sectors who require robust, long-lasting polymeric materials.

Application

• Powder Coatings: A key resin binder for high-quality, durable thermosetting powder coatings used in automotive, appliance, and architectural finishes.
• Industrial & Protective Coatings: Formulated into solvent-based or high-solid coatings that provide exceptional corrosion and chemical resistance for metal substrates, pipelines, and industrial equipment.
• Plastic Additives & Modifiers: Used as a performance additive to enhance the heat resistance, weatherability, and mechanical strength of engineering plastics and composites.
• Adhesives & Sealants: Serves as a base polymer in high-performance structural adhesives and sealants requiring strong bonding and environmental stability.
• Electrical Insulation: Employed in the formulation of insulating varnishes and enamels for wires and electrical components due to its good dielectric properties.
• Inks: Used in specialty printing inks, such as heat-resistant or metal-decorating inks, where durability is paramount.

Quality Control

Our Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance characteristics such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect product performance.
