Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,3-Butanediol, 1,6-Diisocyanatohexane, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, 1,6-Hexanediol And 2-Oxepanone CAS NO 83863-86-9 is a high-performance, aliphatic-aromatic polyester-polyurethane copolymer. This engineered polymer is valued for its excellent balance of mechanical strength, chemical resistance, and processing versatility. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material applications requiring durable, flexible polymer matrices.

Application

• High-Performance Coatings and Paints: Used as a resin binder in industrial, automotive, and protective coatings for enhanced durability, flexibility, and chemical resistance.
• Adhesives and Sealants: Serves as a key polymer component in formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding and elastic properties.
• Elastomers and Thermoplastic Polyurethanes (TPU): A fundamental building block for manufacturing flexible, abrasion-resistant elastomers used in wheels, gaskets, and industrial belts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites to improve toughness and impact resistance.
• Textile and Leather Finishing: Employed in coatings for synthetic leather, waterproof textiles, and other fabric treatments to provide a soft feel and high durability.
• Encapsulants and Potting Compounds: Used in electronics and electrical applications to protect components, offering good insulation and environmental sealing properties.
