Description

1,3-Benzenedicarboxylic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, Hexanedioic Acid And 1,3-Isobenzofurandione is a high-performance, saturated polyester resin designed for demanding industrial applications. This polymer offers a unique balance of chemical resistance, thermal stability, and mechanical strength, making it a critical component in advanced coating and composite systems. It is primarily sought by manufacturers in the coatings, adhesives, and specialty plastics industries for formulating durable, high-quality finishes and engineered materials.

Application

• Powder Coatings: A key resin binder for creating durable, weather-resistant, and decorative finishes on metal substrates for automotive, appliance, and architectural applications.
• Industrial & Protective Coatings: Used in high-performance liquid coatings that require excellent chemical resistance and adhesion for pipelines, storage tanks, and industrial equipment.
• Can & Coil Coatings: Provides the necessary flexibility, formability, and corrosion protection for coatings applied to metal coils and food/beverage containers.
• Adhesives & Sealants: Serves as a base polymer in formulations requiring strong bonding, thermal stability, and resistance to environmental stress.
• Engineering Plastics & Composites: Used as a modifier or primary resin in composite materials to enhance mechanical properties, dimensional stability, and heat resistance.
• Electrical Insulation: Suitable for wire enamel and insulating varnishes due to its good dielectric properties and thermal endurance.

Quality Control

Our production of this polyester resin adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously tested. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our quality system is designed to support formulations requiring compliance with various industrial and regulatory standards.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from strong oxidizing agents.
