In the vast landscape of industrial chemicals, certain compounds stand out for their unique properties and broad applicability. Nadic Anhydride (CAS 826-62-0), also known as 5-Norbornene-2,3-dicarboxylic anhydride, is one such essential organic intermediate. Its bicyclic structure and reactive anhydride group make it invaluable in the production of advanced polymers, coatings, and specialty chemicals. As a leading manufacturer and supplier in China, we provide a detailed look at Nadic Anhydride, covering its critical properties, key applications, and the advantages of sourcing it from our facilities.

Nadic Anhydride is characterized by its physical appearance as a white solid, with a melting point typically ranging from 158-164°C, indicating good thermal stability for processing. Its molecular formula is C9H8O3, and its CAS number is 826-62-0. The compound's reactivity is primarily attributed to its anhydride functional group, which readily undergoes hydrolysis to form the corresponding dicarboxylic acid. This chemical nature is crucial for its role in polymerization and cross-linking reactions. For procurement managers seeking reliable raw materials, understanding these fundamental properties is key to successful formulation.

The applications of Nadic Anhydride are diverse and impactful across several industries. In the coatings sector, it serves as a vital comonomer in unsaturated polyester resins. Its incorporation leads to significant improvements in crucial performance metrics, including enhanced air-drying capabilities, superior heat resistance, better surface smoothness, elevated electrical properties, and improved corrosion resistance when compared to resins based on phthalic anhydride or THPA. This makes Nadic Anhydride a preferred choice for high-performance coatings used in demanding environments.

Furthermore, Nadic Anhydride is widely employed as an epoxy resin curing agent. Its ability to create densely cross-linked networks results in cured epoxy systems that exhibit exceptional resistance to environmental factors, outstanding heat stability, and excellent electrical insulation characteristics. This makes it ideal for applications in electrical casting, laminating, and powder molding. R&D scientists exploring new material formulations will find Nadic Anhydride to be a versatile tool for achieving superior material properties.

Beyond these major uses, Nadic Anhydride also functions as a modifying agent for various other resins, including alkyd, urea formaldehyde, and melamine resins. It also finds niche applications in the synthesis of insecticides and plasticizers.
