Description

1,3-Cyclohexanediamine, Polymer With 1,2-Ethanediamine, α-Hydro-ω-Hydroxypoly( Oxy-1,4-Butanediyl) And 1,1'-Methylenebis[4-Isocyanatobenzene] is a high-performance polyurethane prepolymer or polyurea-based resin intermediate. This specialized polymer is engineered to deliver exceptional durability, chemical resistance, and flexibility in demanding industrial applications. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for formulating advanced composite materials and protective systems.

Application

• High-Performance Coatings: Used as a key resin component in industrial and marine protective coatings, offering superior abrasion, corrosion, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives and flexible sealants with excellent bonding strength and environmental stability.
• Elastomer Production: Employed in the manufacture of cast polyurethane/polyurea elastomers for applications requiring high tensile strength and impact resistance.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for the automotive and aerospace sectors.
• Waterproofing Membranes: Utilized in the formulation of spray-applied, seamless waterproofing and containment liners.
• Industrial Flooring: A critical ingredient in high-traffic, chemical-resistant flooring systems for factories and warehouses.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized for critical parameters including isocyanate (NCO) content, viscosity, and amine value to guarantee consistent performance in your formulations. Certificates of Analysis (COA) are available upon request, and our quality system supports compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from heat, open flames, and sources of moisture. Under these conditions, the product is typically stable for 12 months from the date of manufacture.
