Description

Alcohols, C8-14, .gamma.-.omega.-perfluoro, reaction products with epichlorohydrin, tetrahydrofuran homopolymer and N,N,2-tris(6-isocyanatohexyl)imidodicarbonic diamide CAS NO 118102-38-8 is a specialized fluorinated polyurethane prepolymer, engineered by reacting perfluoroalkyl alcohols with epichlorohydrin and a trifunctional isocyanate. This compound matters for its unique combination of exceptional hydrophobicity, oleophobicity, and chemical resistance imparted by the perfluoroalkyl segments, coupled with the versatile reactivity of isocyanate groups. It is primarily needed by formulators in the coatings, textiles, and high-performance materials sectors seeking to impart durable, low-surface-energy properties.

Application

• High-Performance Coatings & Sealants: As a key component in formulating durable, water- and oil-repellent protective coatings for metals, concrete, and textiles.
• Advanced Textile Finishing: For creating permanent stain-resistant and hydrophobic finishes on technical fabrics, outdoor gear, and upholstery.
• Specialty Elastomers & Adhesives: Used in the synthesis of fluorinated polyurethane elastomers and adhesives requiring enhanced chemical and environmental stability.
• Release Coatings & Mold Agents: As a release agent precursor for industrial molding processes, providing excellent non-stick properties.
• Paper & Packaging Treatments: To impart grease resistance and moisture barrier properties to specialty paper and packaging materials.
• Composite Material Modification: As a surface modifier or crosslinker to improve the interfacial properties and performance of polymer composites.

Quality Control

Our production of this fluorinated prepolymer adheres to strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including monitoring of isocyanate content (NCO%), viscosity, and the presence of key functional groups. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent premature reaction and degradation. Recommended storage temperature is between 2°C and 25°C in a cool, dry, and well-ventilated area. Keep away from heat, open flames, and sources of moisture.
