Description

Ammonium 2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptanoate is the ammonium salt of a highly fluorinated carboxylic acid, offering unique surface-active and hydrophobic properties due to its perfluorinated alkyl chain. This compound is valued for its ability to impart exceptional oil, water, and stain repellency in advanced material formulations. It serves as a critical fluorochemical intermediate for industries developing high-performance coatings, surfactants, and specialty polymers where low surface energy and chemical resistance are paramount.

Application

• Fluorinated Surfactant & Emulsifier: Used in the formulation of fire-fighting foams, coatings, and emulsion polymerization processes requiring superior wetting and leveling.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR/DOR) to fabrics, carpets, and technical textiles.
• Paper & Packaging Coatings: Provides grease resistance and barrier properties for food packaging and specialty papers.
• Specialty Polymer Synthesis: Acts as a monomer or modifier in the production of fluoropolymers and fluoroelastomers with enhanced chemical and thermal stability.
• Surface Modifier for Electronics: Used in anti-fingerprint coatings and moisture-protective layers for electronic components and displays.
• Leather & Upholstery Treatment: Delivers stain and soil resistance to finished leather goods and furniture.

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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
