Description

1,4-Butanediol, Polymer With 1,1-Methylenebis4-Isocyanatocyclohexane, Methyloxirane And Oxirane (CAS No. 111325-20-3) is a specialized polyurethane prepolymer or polyol derivative designed for high-performance applications. This advanced polymer offers a unique combination of flexibility, chemical resistance, and durability derived from its cycloaliphatic isocyanate and polyether/glycol backbone. It is primarily utilized by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Used as a key resin component in polyurethane coatings for industrial, automotive, and marine applications, providing excellent weatherability and chemical resistance.
• Elastomers and Sealants: Serves as a prepolymer for manufacturing flexible and durable polyurethane elastomers, gaskets, and sealants.
• Adhesives and Binders: Acts as a polyol component in structural and laminating adhesives, offering strong bonding and toughness.
• Composite Materials: Employed in the production of fiber-reinforced composites and potting compounds for the electronics and aerospace sectors.
• Specialty Resins: Formulated into resins for 3D printing (e.g., SLA/DLP), castable molds, and other advanced manufacturing processes.

Quality Control

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

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 / 59-77°F). This product is hygroscopic (moisture-sensitive). Containers must be kept tightly sealed under a dry atmosphere (e.g., under nitrogen blanket) to prevent moisture absorption and premature reaction, which can affect product performance.
