Description

2,5-Furandione, Polymer With 2,2'-Oxybis[Ethanol], 1,2-Propanediol And 3A,4,7,7A-Tetrahydro-4,7-Methano-1H-Indene CAS NO 68928-71-2 is a specialized polymeric resin derived from maleic anhydride, diethylene glycol, propylene glycol, and dicyclopentadiene. This engineered polymer is valued for its excellent cross-linking potential, adhesion properties, and chemical resistance, making it a critical intermediate for high-performance coatings and composites. It is primarily sought by formulators in the industrial coatings, adhesives, and advanced material sectors who require durable, chemically resistant binders.

Application

• High-Performance Industrial Coatings: Used as a key resin binder in corrosion-resistant coatings for metal substrates, pipelines, and marine applications.
• Adhesives and Sealants: Serves as a reactive polymer component in structural adhesives and sealants requiring strong adhesion and environmental durability.
• Composite Materials: Acts as a matrix resin or cross-linking agent in fiber-reinforced plastics (FRP) and other composite systems.
• Electrical Encapsulation: Employed in potting compounds and encapsulants for electronic components due to its insulating and protective properties.
• Automotive Underbody Coatings: Formulated into protective coatings that resist stone chipping, moisture, and road chemicals.
• Printing Inks: Utilized in specialty printing inks where chemical resistance and fast curing are essential.

Quality Control

Our production of this specialty polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to ensure the material meets your formulation requirements. We operate under a quality management system aligned with industrial best practices.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat sources and open flame. Under recommended storage conditions, the product is typically stable. For long-term storage, consider under an inert atmosphere to minimize potential oxidation.
