Description

1,2-Ethanediamine, Polymer With .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) And 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyurethane prepolymer or polyurea derivative, synthesized from a polyether polyol and isophorone diisocyanate (IPDI), chain-extended with ethylenediamine. This compound matters as a high-performance polymer intermediate, offering a unique balance of flexibility, chemical resistance, and mechanical strength derived from its segmented block copolymer structure. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as manufacturers of advanced composites and specialty resins seeking enhanced durability and processing characteristics.

Application

• High-Performance Coatings: Used as a key resin component in protective and decorative coatings for automotive, industrial, and marine applications, providing excellent weatherability and chemical resistance.
• Elastomers and Sealants: Serves as a prepolymer for manufacturing polyurea and polyurethane elastomers, gaskets, and sealants that require high tensile strength, abrasion resistance, and fast cure times.
• Adhesives and Binders: Employed in formulating structural and specialty adhesives, as well as binders for composites, offering strong adhesion to various substrates.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve impact resistance and interfacial bonding.
• Waterproofing Membranes: A crucial ingredient in spray-applied polyurea waterproofing and lining systems for roofs, containment areas, and infrastructure.
• 3D Printing Resins: Potential use as a component in advanced photopolymer or thermoset resin formulations for additive manufacturing.

Quality Control

Our production of this polymer intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency for demanding industrial applications. Key parameters such as NCO content, viscosity, and equivalent weight are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing assay, physical properties, and impurity profiles is provided with each shipment to guarantee it meets your formulation specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. This material is moisture-sensitive (hygroscopic) and may react with water; ensure containers are sealed under a dry atmosphere (e.g., nitrogen) after opening to prevent degradation and maintain performance.
