Description

Octadecafluoroundecanedioic Acid Dimethyl Ester is a high-purity fluorinated building block essential for advanced material synthesis. This compound is valued for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to polymers and surface coatings. It is primarily sought by R&D and manufacturing sectors in the specialty chemical, high-performance polymer, and surface treatment industries for developing next-generation fluorinated materials.

Application

• Fluorinated Polymer Synthesis: A key monomer for producing high-performance fluoropolymers and fluorinated polyesters with enhanced stability.
• Surface Modifier & Coating Additive: Imparts water- and oil-repellent (omniphobic) properties to textiles, papers, and protective coatings.
• Pharmaceutical & Agrochemical Intermediates: Serves as a versatile fluorinated synthon in the development of bioactive molecules.
• Lithography & Electronics: Used in the formulation of advanced photoresists and dielectric materials for semiconductor manufacturing.
• Specialty Surfactants & Lubricants: Acts as a precursor for creating highly stable, fluorinated surfactants and high-temperature lubricants.
