Description

Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-hydro-.omega.-hydroxy-, polymer with 1,3-diisocyanatomethylbenzene, 5-amino-1,3,3-trimethylcyclohexanemethanamine-terminated is a specialized polyurethane prepolymer or polyol derivative, known for its reactive amine termination. This chemical structure is engineered to provide enhanced reactivity, adhesion, and mechanical properties in formulated systems. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for developing high-performance, durable products.

Application

• High-Performance Coatings: As a key component in polyurethane-based industrial, protective, and marine coatings for superior chemical resistance and durability.
• Structural Adhesives & Sealants: Used in formulations requiring strong bonding, flexibility, and environmental stability for automotive, aerospace, and construction applications.
• Elastomer Production: Serves as a prepolymer or chain extender in the manufacture of castable and thermoplastic polyurethane elastomers.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Waterproofing Membranes: A critical raw material in liquid-applied and sheet membrane systems for roofing and infrastructure.
• Industrial Resins: Utilized in resin formulations for potting, encapsulation, and molding applications requiring toughness.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistency in amine value, viscosity, isocyanate content (NCO%), and moisture levels. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

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 moisture-sensitive (hygroscopic) and should be kept under a dry, inert atmosphere (e.g., nitrogen) to prevent degradation and maintain reactivity.
