Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With 1,2-Ethanediol And 1,6-Hexanediol CAS NO 36201-75-9 is a high-performance copolyester resin derived from dimethyl terephthalate (DMT), ethylene glycol, and hexanediol. This engineered polymer is valued for its excellent balance of mechanical properties, chemical resistance, and processability, making it a versatile material for demanding applications. It is primarily sought by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Powder Coatings: As a key resin binder for durable, weather-resistant, and decorative finishes on metal substrates for automotive, architectural, and appliance applications.
• High-Solid and Solvent-Based Coatings: Providing excellent film formation, hardness, and chemical resistance for industrial maintenance and protective coatings.
• Hot-Melt Adhesives: Imparting flexibility, adhesion strength, and thermal stability for packaging, textiles, and product assembly.
• Plasticizers and Modifiers: Used as a polymeric plasticizer or modifier to improve the toughness and low-temperature flexibility of PVC and other polymers.
• Ink Resins: Serving as a component in specialty printing inks requiring good pigment wetting, gloss, and substrate adhesion.
• Fiber and Film Modification: Enhancing the properties of polyester fibers and films for technical textiles and specialty packaging.

Quality Control

Our copolyester resins are manufactured under strict quality management systems 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 each shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep containers tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
