Description

1,3-Butanediol, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyurethane prepolymer or polyol derivative, designed to deliver enhanced performance characteristics in advanced polymer formulations. This compound matters for its role as a key building block, offering tailored reactivity, crosslinking density, and final material properties. Industrial manufacturers in coatings, adhesives, sealants, and elastomers (CASE) sectors require this material to develop high-performance, durable products.

Application

• High-Performance Coatings: Used as a reactive component in polyurethane coatings for industrial, automotive, and protective applications, providing excellent chemical resistance, adhesion, and weatherability.
• Advanced Adhesives & Sealants: Serves as a backbone resin in formulating structural adhesives and flexible sealants, contributing to strong bonding and elasticity.
• Specialty Elastomers: A critical raw material for manufacturing castable, thermoplastic, or millable polyurethane elastomers used in rollers, gaskets, and wear-resistant parts.
• Composite Materials: Employed in the production of fiber-reinforced plastics and composite matrices, enhancing mechanical strength and interfacial bonding.
• Binder Systems: Acts as a polymeric binder in foundry sands, abrasives, and non-woven materials, improving cohesion and thermal stability.
• Flexible & Rigid Foams: Can be utilized in formulating specialized polyurethane foam systems where specific reactivity profiles and physical properties are required.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict protocols to guarantee batch-to-batch consistency in key parameters such as NCO content, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry atmosphere (e.g., under nitrogen) to prevent moisture absorption and premature reaction. Recommended storage temperature is 15-25°C. Keep away from heat, sparks, and open flame.
