Description

1,2-Ethanediol, Polymer With 1,6-Diisocyanato-2,4,4-Trimethylhexane is a specialized polyurethane prepolymer derived from the reaction of ethylene glycol and a branched aliphatic diisocyanate. This compound matters as a versatile building block, offering a unique combination of flexibility, hydrolytic stability, and weatherability due to its aliphatic structure. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance, durable products.

Application

• High-Performance Coatings: As a key resin component in automotive clear coats, industrial maintenance paints, and weather-resistant architectural coatings, providing excellent gloss retention and UV stability.
• Elastomers and Sealants: Used in the formulation of flexible, durable elastomers for gaskets, rollers, and weather-stripping, as well as high-strength sealants for construction and automotive applications.
• Adhesives: Serves as a base polymer for structural and laminating adhesives, offering strong bonding performance with good resistance to environmental factors.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to enhance toughness and interfacial adhesion.
• Specialty Binders: Employed in the production of binders for specialty textiles, non-wovens, and abrasives where chemical resistance and flexibility are required.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems. Every batch is characterized for critical parameters including NCO content, viscosity, and residual monomer levels to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent moisture ingress, which can lead to premature polymerization or gelation. Keep away from heat, sparks, and open flame.
