Description

Ethene, Tetrafluoro-, Homopolymer, .Alpha.-Fluoro-.Omega.-(2-Hydroxyethyl)-, Citrate, Reaction Products With 1,6-Diisocyanatohexane is a specialized fluorinated polyurethane prepolymer, representing a high-performance material engineered for demanding applications. This compound matters for its unique combination of chemical resistance, durability, and potential biocompatibility derived from its fluoropolymer backbone and urethane linkages. It is primarily needed by formulators and manufacturers in the advanced coatings, medical device, and specialty adhesive industries seeking to enhance product performance under extreme conditions.

Application

• High-Performance Coatings: Used as a key resin component in industrial and marine coatings requiring exceptional chemical, solvent, and weather resistance.
• Medical Device Coatings: Suitable for creating biocompatible, lubricious, and blood-contacting surface modifications on catheters, guidewires, and implants.
• Specialty Adhesives & Sealants: Serves as a base polymer for adhesives that must maintain integrity in aggressive chemical environments or over wide temperature ranges.
• Release Coatings: Applied in mold release applications for composites and plastics where non-stick properties are critical.
• Optical Fiber Coatings: Potential use in secondary coatings to protect fibers from moisture and mechanical stress.
• Electronic Encapsulants: Employed in potting and encapsulating compounds for electronic components requiring high purity and stability.

Quality Control

Our production of this advanced fluoropolymer is governed by a rigorous quality management system. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as NCO content, viscosity, fluorine content, and residual monomers. Certificates of Analysis (COA) are provided with every shipment, detailing the specific results. We adhere to cGMP principles where applicable, and our facilities are designed to meet the high purity standards required for sensitive applications like medical devices and electronics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is moisture-sensitive (hygroscopic) and may react with atmospheric moisture; containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and open flame. Separate from strong acids, bases, and oxidizing agents.
