Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,4-cyclohexanedimethanol, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 1,1'-methylenebis[4-isocyanatocyclohexane], compd CAS NO 139682-55-6 is a specialized aliphatic polyurethane prepolymer or resin derived from a complex mixture of diols, a diacid, and an aliphatic diisocyanate. This engineered polymer is valued for its excellent weatherability, hydrolysis resistance, and mechanical flexibility, making it a critical raw material for high-performance coatings and elastomers. It is primarily needed by formulators in the automotive, industrial maintenance, and specialty adhesives sectors seeking durable, non-yellowing products.

Application

• High-Performance Coatings: Formulation of two-component (2K) polyurethane topcoats for automotive refinish, aerospace, and industrial equipment requiring superior gloss retention and chemical resistance.
• Elastomers and Sealants: Production of flexible, weather-resistant cast elastomers, gaskets, and sealants for outdoor and marine applications.
• Adhesives and Binders: Used as a key component in structural and laminating adhesives where durability and bond strength under environmental stress are critical.
• Industrial Maintenance Coatings: Base for protective coatings on bridges, pipelines, and storage tanks exposed to harsh UV and corrosive conditions.
• Plastic Modifiers: Acts as a reactive modifier to enhance the toughness, flexibility, and adhesion properties of other polymer systems.
• Specialty Inks and Overprint Varnishes: Provides a durable, flexible film for high-end graphic arts and packaging applications.

Quality Control

Our production of this polyurethane polymer adheres to strict batch-to-batch consistency protocols to ensure reliable performance in downstream formulations. Quality is verified through parameters including NCO content, viscosity, solids content, and color (APHA/Hazen). A comprehensive 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. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is moisture-sensitive (hygroscopic); ensure containers are sealed after use to prevent exposure to atmospheric humidity, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
