Description

Trimethyl-3-[[(pentadecafluoroheptyl)sulphonyl]amino]propylammonium chloride is a high-performance fluorinated quaternary ammonium compound, distinguished by its unique perfluoroalkyl chain. This structure provides exceptional surface activity, chemical stability, and oleophobic/hydrophobic properties, making it a critical material for demanding industrial applications. It is primarily utilized in sectors requiring advanced surface modification, including high-tech coatings, specialty textiles, and fluoropolymer processing.

Application

• As a key fluorosurfactant and leveling agent in high-performance fluoropolymer coatings and paints.
• As a durable water and oil repellent finish for technical textiles, outdoor gear, and protective clothing.
• As a surface modifier and antistatic agent in the production of specialty plastics and polymers.
• As an additive for fire-fighting foams (AFFF) to enhance film-forming and spreading characteristics.
• In the formulation of anti-fogging and anti-soiling coatings for optical and electronic components.
• As a processing aid and mold release agent in fluoroclastomer and high-temperature polymer manufacturing.
• For imparting soil release and stain resistance in carpet and upholstery treatments.
• In research and development of novel biomaterials and medical device coatings with low surface energy.

Quality Control

Our production of Trimethyl-3-[[(pentadecafluoroheptyl)sulphonyl]amino]propylammonium chloride adheres to stringent quality management protocols. Every batch is analyzed to ensure consistent purity, performance, and compliance with relevant industry standards. Comprehensive Certificates of Analysis (COA) documenting identity, assay, impurity profile, and physical specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
