Description

1,3-Benzenedicarboxylic acid, polymer with 1,4-butanediol, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid and 1,1-methylenebis4-isocyanatocyclohexane is a high-performance, aliphatic-aromatic copolyester polyol resin. This specialized polymer is engineered to deliver a unique balance of flexibility, chemical resistance, and durability for demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Polyurethane Coatings: Used as a polyol component in two-component (2K) polyurethane systems for industrial, automotive, and marine coatings requiring excellent weatherability, gloss retention, and chemical resistance.
• Elastomers and Sealants: Serves as a key building block in the production of flexible polyurethane elastomers, gaskets, and high-strength sealants that demand resilience and durability.
• Adhesives and Binders: Formulated into structural and laminating adhesives where strong bonding, flexibility, and resistance to environmental stress are paramount.
• Specialty Resins and Modifiers: Acts as a polymeric modifier to improve the toughness, flexibility, and adhesion properties of other resin systems, such as epoxies or acrylics.
• Industrial and Protective Linings: Utilized in linings and protective coatings for tanks, pipes, and concrete floors that are exposed to aggressive chemicals or abrasion.

Quality Control

Our production of this advanced polyol adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light and moisture. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flames. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
