Description

Methyl Perfluoroundecanoate 96 is a high-purity fluorinated ester compound, identified by CAS NO 203302-98-1. This specialty chemical is valued for its exceptional hydrophobic and oleophobic properties, derived from its long perfluoroalkyl chain. It serves as a critical intermediate and performance additive for manufacturers in the coatings, surface treatment, and specialty polymer industries seeking to impart advanced surface characteristics.

Application

• Fluorinated Surfactant & Polymer Intermediate: A key building block for synthesizing high-performance fluorosurfactants and fluoropolymers.
• Water & Oil Repellent Coatings: Used to formulate durable surface treatments for textiles, leather, paper, and non-woven fabrics.
• Specialty Additives: Imparts low surface energy and release properties in lubricants, mold release agents, and anti-fouling coatings.
• Electronics & Semiconductor Industry: Employed in the formulation of protective coatings and anti-reflective layers.
• Fire-Fighting Foams (Legacy/Formulation R&D): Historically used as a component in aqueous film-forming foams (AFFF); relevant for research and formulation studies.
• Chemical Synthesis: Acts as a versatile precursor for further chemical modifications to create other perfluorinated derivatives.
