Description

1,3-Isobenzofurandione, Polymer With 2,5-Furandione, 2,2'-Oxybis[Ethanol] And 3A,4,7,7A-Tetrahydro-4,7-Methano-1H-Indene is a specialized polymeric resin derived from phthalic anhydride, maleic anhydride, diethylene glycol, and dicyclopentadiene, designed for high-performance applications. This compound matters for its ability to form durable, chemically resistant coatings and matrices with excellent adhesion and thermal stability. It is primarily needed by manufacturers in the advanced composites, industrial coatings, and specialty adhesives sectors seeking robust polymeric materials.

Application

• High-performance industrial coatings for metal substrates requiring corrosion and chemical resistance.
• Matrix resin for fiber-reinforced composites in automotive and aerospace components.
• Curing agent or modifier in epoxy and polyester resin systems to enhance flexibility and toughness.
• Binder for specialty adhesives and sealants with demanding environmental durability.
• Electrical insulation materials such as potting compounds and encapsulants.
• Additive for printing inks to improve gloss, adhesion, and drying properties.

Quality Control

Our production of this polymeric resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including determination of acid value, viscosity, and color, to meet precise customer specifications. A Certificate of Analysis (COA) documenting all critical parameters is provided with every shipment.

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/59-77°F). Keep away from strong acids and organic solvents. The container must be kept tightly sealed to prevent moisture absorption and contamination.
