Description

1H,1H,2H,2H-Perfluoroundecanoic Acid Potassium Salt is a high-value fluorinated surfactant and intermediate, prized for its unique combination of hydrophobicity, oleophobicity, and chemical stability imparted by its perfluoroalkyl chain. This compound is essential for creating surfaces and materials with exceptional water, oil, and stain repellency. It is a critical raw material for manufacturers in the specialty chemicals, advanced materials, and performance coatings industries seeking to develop next-generation functional products.

Application

• Fluorinated Surfactant & Emulsifier: Key ingredient in fire-fighting foams (AFFF), coatings, and polymer dispersions where superior wetting and leveling are required.
• Surface Modification Agent: Used to impart oil, water, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Polymer Additive: Acts as a processing aid and surface property modifier in fluoropolymers and high-performance engineering plastics.
• Lithography & Electronics: Employed in photoresist formulations and as a surfactant in electronic chemical manufacturing for semiconductor processing.
• Specialty Coatings: Formulation component for creating anti-fingerprint, easy-clean, and anti-graffiti coatings on various substrates.
• Chemical Intermediate: Serves as a building block for synthesizing more complex fluorinated compounds, including pharmaceuticals and agrochemicals.

Quality Control

Our production of 1H,1H,2H,2H-Perfluoroundecanoic Acid Potassium Salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure consistent purity and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
