4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,17,17-Nonacosafluoro-2-Hydroxyheptadecyl Dihydrogen Phosphate is a high-value, specialty fluorinated phosphate ester, distinguished by its unique perfluorinated alkyl chain. This structure provides exceptional surface activity, chemical resistance, and thermal stability, making it a critical performance additive. It is primarily sought after by advanced material scientists and formulators in the coatings, electronics, and specialty polymer industries for its ability to impart low surface energy and enhance durability.

Application

• Fluorinated Surfactant & Leveling Agent: A key component in high-performance fluoropolymer coatings, paints, and varnishes to improve wetting, flow, and anti-cratering properties.
• Surface Modifier for Electronics: Used in photoresist formulations and as an additive in electronic chemicals to control surface tension and enhance coating uniformity on semiconductor wafers.
• Textile & Leather Treatment: Imparts oil, water, and stain repellency to fabrics, carpets, and leather goods as a durable fluorochemical finish.
• Firefighting Foam Concentrate (Legacy/Formulation R&D): Historically used as a raw material in the synthesis of certain fluorosurfactants for aqueous film-forming foam (AFFF).
• Specialty Polymer Additive: Acts as a processing aid and release agent in the manufacture of high-temperature engineering plastics and elastomers.
• Research & Development: Serves as a building block or intermediate in organic synthesis for novel fluorinated compounds in academic and industrial R&D labs.
