Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 1,1-methylenebis4-isocyanatocyclohexane is a high-performance, aliphatic polyurethane prepolymer or resin derived from a complex, multi-component reaction. This specialized polymer is engineered to deliver exceptional weatherability, chemical resistance, and mechanical properties, making it a critical raw material for demanding industrial applications. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for formulating premium-grade products that require long-term durability and clarity.

Application

• High-Performance Coatings: Used as a key resin in automotive clear coats, industrial maintenance paints, and protective marine coatings where superior UV resistance and gloss retention are critical.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives, laminating agents, and flexible sealants that demand strong bonding and resistance to environmental stress.
• Elastomers and Castable Urethanes: Formulated into durable elastomeric components, rollers, gaskets, and wear-resistant parts that benefit from its aliphatic (non-yellowing) nature.
• Optical and Electronic Encapsulants: Employed in potting compounds and encapsulants for LEDs and sensitive electronic components due to its potential for clarity and stability.
• Specialty Inks and Overprint Varnishes: Provides a durable, scratch-resistant, and glossy finish in premium printing and packaging applications.

Quality Control

Our production of this advanced polyurethane polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Quality is verified through a suite of analytical tests including NCO content, viscosity, solids content, color, and acid number. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically between 15°C and 25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
