Description

Imidodicarbonic diamide, N,N',2-tris(6-isocyanatohexyl)-, polymer with .alpha.-hydro.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] ether with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol is a specialized polyurethane prepolymer based on a complex isocyanate-functionalized imidodicarbonic diamide core. This compound is engineered to deliver superior performance as a reactive intermediate in high-performance coating and adhesive formulations. It is primarily sought by manufacturers in the industrial coatings, specialty adhesives, and advanced elastomers sectors who require enhanced durability, chemical resistance, and tailored cross-linking properties.

Application

• High-Performance Industrial Coatings: Used as a key resin component in protective coatings for metal, concrete, and plastic substrates, offering excellent abrasion and chemical resistance.
• Specialty Adhesives & Sealants: Serves as a reactive prepolymer in the formulation of polyurethane-based adhesives and sealants for automotive, construction, and aerospace applications.
• Elastomer Production: Acts as a cross-linking agent in the manufacture of castable and thermoplastic polyurethane elastomers for gaskets, wheels, and industrial parts.
• Composite Materials: Utilized in the production of fiber-reinforced composites, enhancing the interfacial bonding between the matrix and reinforcing fibers.
• Waterproofing Membranes: A critical component in liquid-applied waterproofing systems for roofs, bridges, and containment structures.
• Electrical Potting & Encapsulation: Provides robust environmental protection and insulation for sensitive electronic components.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature curing and viscosity increase.
