Description

Nadic Anhydride CAS NO 826-62-0 is a high-purity, bicyclic anhydride monomer widely used as a curing agent and crosslinker in polymer chemistry. Its rigid, fused-ring structure is critical for imparting enhanced thermal stability, mechanical strength, and chemical resistance to the final polymeric materials. This product is essential for manufacturers in the advanced composites, electronics, and specialty coatings industries seeking to develop high-performance, durable end-products.

Application

• Epoxy Resin Curing Agent: Used to cure epoxy resins, resulting in networks with excellent high-temperature performance and toughness for aerospace and automotive composites.
• Polyimide Synthesis: Serves as a key monomer in the production of polyimide resins and films, which are vital for flexible printed circuits (FPCs) and high-temperature electrical insulation.
• Alkyd Resin Modifier: Incorporated to improve the hardness, drying time, and chemical resistance of alkyd-based surface coatings and paints.
• Unsaturated Polyester Resins (UPR): Acts as a crosslinking agent to enhance the thermal and mechanical properties of UPRs used in fiber-reinforced plastics (FRP).
• Adhesive Formulations: Employed in high-performance structural adhesives where thermal endurance and bond strength are paramount.
• Research & Development: Utilized in academic and industrial R&D for synthesizing novel polymers with tailored properties.

Quality Control

Our Nadic Anhydride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical properties is provided with each shipment to guarantee consistency and 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 (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture.
