Description

Octanoic Acid 2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl Ester is a highly fluorinated ester derivative of octanoic acid, valued for its unique combination of lipophilicity and extreme hydrophobicity imparted by the perfluorinated alkyl chain. This compound is engineered to provide exceptional chemical and thermal stability, along with outstanding oil and water repellency. It is a critical specialty chemical for advanced material science, serving as a key intermediate or additive in the formulation of high-performance coatings, lubricants, and surface modifiers.

Application

• High-Performance Lubricants & Greases: Acts as a base oil or additive to enhance lubricity, reduce friction, and provide extreme pressure (EP) properties in demanding industrial and aerospace applications.
• Water & Oil Repellent Coatings: Used as a key fluorochemical building block for creating durable, stain-resistant, and easy-to-clean surfaces on textiles, leather, paper, and non-woven fabrics.
• Specialty Polymer Modification: Serves as a monomer or plasticizer to impart hydrophobicity, chemical resistance, and low surface energy to polymers like polyurethanes, acrylics, and epoxies.
• Electronics & Semiconductor Industry: Employed in formulations for protective coatings on circuit boards and electronic components due to its excellent dielectric properties and moisture barrier capabilities.
• Fire-Fighting Foams (Legacy/Formulation R&D): Historically used as a fluorosurfactant precursor in aqueous film-forming foam (AFFF) formulations; relevant for research into alternative chemistries.
• Surface Treatment for Metals & Glass: Provides a thin, durable hydrophobic layer that improves corrosion resistance and facilitates water beading.
