Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid, 2,2-Dimethyl-1,3-Propanediol, 1,2-Ethanediol And 1,6-Hexanediol is a high-performance, amorphous copolyester resin engineered for superior durability and processing versatility. This material matters for formulators seeking a unique balance of chemical resistance, thermal stability, and mechanical properties not found in standard polyesters. It is primarily needed by manufacturers in the coatings, adhesives, and specialty plastics industries for creating advanced, high-value end products.

Application

• High-Performance Industrial Coatings: Used as a resin binder in coil, can, and automotive coatings requiring excellent weatherability and chemical resistance.
• Powder Coatings: Serves as a key polyester component for formulations demanding good flow, leveling, and impact resistance for architectural and functional applications.
• Thermoplastic Polyester Elastomers (TPEE): Acts as a hard segment to enhance the modulus, heat resistance, and dimensional stability of flexible copolymers.
• Hot-Melt Adhesives: Provides strong adhesion, thermal stability, and flexibility for bonding in automotive, textile, and packaging applications.
• Ink Resins: Utilized in specialty printing inks where fast drying, gloss, and substrate adhesion are critical performance factors.
• Engineering Plastics Modification: Employed as a compatibilizer or toughening agent to improve the impact strength and processability of blends.

Quality Control

Our copolyester products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with stringent industry specifications. Key parameters such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are monitored. Certificates of Analysis (COA) detailing these specifications are available upon request, supporting your quality assurance and regulatory needs.

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); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect processing and final product properties.
