Description

2,2,3,3,4,4,5,5,6,6,7,7,7-Tridecafluoro-1,1-Heptanediol is a highly fluorinated diol compound characterized by its unique perfluoroalkyl chain, which imparts exceptional hydrophobicity, oleophobicity, and chemical stability. This structure makes it a critical intermediate for synthesizing advanced fluorinated polymers, surfactants, and surface modifiers. It is essential for industries requiring materials with low surface energy, high thermal stability, and resistance to harsh chemicals and solvents.

Application

• Fluorinated Polymer Synthesis: A key monomer for producing high-performance fluoropolymers and fluorinated polyurethanes with enhanced weather resistance and low friction coefficients.
• Specialty Surfactants & Coatings: Used to manufacture fluorosurfactants and additives for coatings, inks, and adhesives to improve leveling, wetting, and anti-foaming properties.
• Surface Modification Agents: Imparts oil, water, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Electronic Materials: Serves as a building block for dielectric materials, encapsulants, and photoresists in the semiconductor and electronics industries.
• Pharmaceutical & Agrochemical Intermediates: Used in the synthesis of fluorinated active ingredients and prodrugs to alter bioavailability and metabolic stability.
• Advanced Lubricants & Greases: Contributes to the formulation of high-temperature, chemically resistant lubricants for demanding industrial applications.
