Description

Hexanedioic acid, polymer with 1,4-butanediol, 1,6-diisocyanatohexane, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and methyloxirane is a high-performance, multi-component polyurethane-polyol hybrid polymer. This engineered material is valued for its versatile property profile, offering a balance of flexibility, chemical resistance, and durability. It is primarily utilized by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop advanced polyurethane systems with tailored performance characteristics.

Application

• High-Performance Coatings: Used as a key resin component in two-component (2K) polyurethane coatings for automotive, industrial, and protective applications, providing excellent gloss, chemical resistance, and weatherability.
• Advanced Adhesives & Sealants: Serves as a polyol backbone in structural and elastic adhesives, offering strong bonding strength, flexibility, and durability for construction, automotive assembly, and composite bonding.
• Specialty Elastomers: Formulated into castable, thermoplastic, or millable polyurethane elastomers for parts requiring high abrasion resistance, such as rollers, wheels, gaskets, and industrial linings.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites, enhancing interfacial adhesion and impact resistance.
• Flexible Foams & Cushioning: Can be tailored for use in the production of high-resilience and specialty flexible polyurethane foams.
• Industrial & Maintenance Paints: A critical ingredient in heavy-duty maintenance paints and linings for metal, concrete, and other substrates exposed to harsh environments.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value (OH#), acid value, viscosity, color, and moisture content to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). This product is moisture-sensitive (hygroscopic); ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect performance.
