Description

Phosphoric Acid Tris(1H,1H,5H-Octafluoro-n-Pentyl) Ester is a highly fluorinated organophosphate ester, a specialty chemical prized for its unique combination of properties derived from its perfluorinated alkyl chains. This compound matters for its exceptional chemical and thermal stability, low surface energy, and hydrophobic/oleophobic characteristics, making it a critical performance additive. Industrial users in sectors such as advanced materials, specialty coatings, and high-performance lubricants need it to impart surface modification, release, and anti-fouling properties.

Application

• Surface Modification Agent: Used to create low-energy, non-stick, and water/oil-repellent surfaces on textiles, paper, and polymers.
• Specialty Additive for Coatings and Inks: Imparts leveling, wetting, and anti-foaming properties in high-performance fluoropolymer coatings and printing inks.
• Release Agent and Mold Lubricant: Acts as an effective internal or external release agent in plastics, rubber, and composite material processing.
• Fire-Resistant Fluid Formulations: Serves as a key component in specialized hydraulic fluids and lubricants requiring high thermal and chemical stability.
• Electronic Chemicals: Potential use as a surfactant or additive in electronics cleaning solutions and for surface treatment of components.
• Research & Development: Employed as a building block or intermediate in the synthesis of novel fluorinated materials and surfactants.
