Description

Methyl Perfluorooctadecanoate is a high-performance fluorinated ester compound, valued for its exceptional chemical inertness, thermal stability, and hydrophobic/oleophobic properties. This makes it a critical functional additive and intermediate in advanced material science and specialty chemical synthesis. It is primarily sought after by manufacturers in the coatings, polymer, and electronics industries for developing high-value, durable products.

Application

• As a key surface modifier in high-performance, stain-resistant, and water-repellent coatings and textiles.
• As a processing aid and release agent in the manufacture of fluoropolymers and other high-temperature plastics.
• As a hydrophobic/oleophobic additive for advanced lubricants and greases used in demanding environments.
• As a chemical intermediate for synthesizing more complex fluorinated surfactants and specialty chemicals.
• In the formulation of anti-fogging and anti-reflective coatings for optical and electronic components.
• For research and development of novel biomedical materials requiring non-stick or biocompatible surfaces.

Quality Control

Our Methyl Perfluorooctadecanoate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong alkalis. Recommended storage temperature is between 15°C and 25°C. The container must be kept tightly sealed to prevent moisture absorption and contamination.
