Description

2-Oxepanone, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyurethane prepolymer or resin intermediate, identified by CAS number 55636-48-1. This compound is engineered to deliver enhanced performance characteristics such as flexibility, chemical resistance, and durability in final cured materials. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to formulate high-performance polyurethane systems.

Application

• High-Performance Coatings: Used as a key resin component in protective and decorative coatings for automotive, industrial, and marine applications, offering excellent weatherability and abrasion resistance.
• Advanced Adhesives & Sealants: Serves as a prepolymer in formulating structural adhesives and flexible sealants with strong bonding strength and environmental durability.
• Specialty Elastomers: Employed in the production of castable and thermoplastic polyurethane elastomers for gaskets, rollers, and industrial parts requiring toughness.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve impact resistance and interfacial adhesion.
• Encapsulation & Potting Compounds: Utilized in electronics and electrical applications to create protective, insulating, and shock-absorbent encapsulants.
• Flexible Foams and Cushioning: Can be formulated into specialized flexible polyurethane foams for technical and comfort applications.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, hydroxyl value, and residual monomer levels to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting compliance with relevant industry standards.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures typically between 15°C and 25°C. Keep away from heat, open flames, and sources of ignition. Due to the presence of reactive isocyanate groups, protect from atmospheric moisture to prevent premature curing or gelation.
