Description

Trimellitic Anhydride, Phthalic Anhydride, Neopentyl Glycol, Adipicacid Polymer CAS NO 38702-16-8 is a specialized polymeric material synthesized from key monomers including trimellitic anhydride, phthalic anhydride, neopentyl glycol, and adipic acid. This engineered polymer is valued for its ability to impart enhanced thermal stability, chemical resistance, and mechanical properties to final formulations. It is primarily sought by manufacturers in the coatings, adhesives, and advanced resin industries seeking to develop high-performance, durable products.

Application

• As a key resin component in high-temperature and corrosion-resistant industrial coatings and powder coatings.
• In the formulation of specialty adhesives and sealants requiring excellent weatherability and bond strength.
• As a modifier or cross-linking agent in the production of unsaturated polyester resins (UPR) for composites.
• For manufacturing alkyd resins with improved flexibility and durability for surface coatings.
• In the synthesis of plasticizers and polymeric materials for specialty applications.
• As an intermediate in the production of electrical insulation materials and encapsulants.

Quality Control

Our Trimellitic Anhydride, Phthalic Anhydride, Neopentyl Glycol, Adipicacid Polymer undergoes rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as acid value, hydroxyl value, viscosity, and color are strictly monitored. Certificates of Analysis (COA) documenting all relevant specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from sources of heat, sparks, and open flame. As a polymeric material, it should be protected from excessive moisture to prevent potential clumping or property changes.
