Vanconol® FPI-S100P Series Imidazoline Quaternary Ammonium Corrosion Inhibitors

Product Overview

Vanconol® imidazoline quaternary ammonium salts are produced by quaternization modification of fatty acid-based imidazolines. The products offer good water solubility, are non-toxic and contain no heavy metals, and are suitable for formulating oil and gas field corrosion inhibitors and petroleum refining corrosion inhibitors. They can also be used as cationic surfactants in industrial cleaning, waterborne resin manufacturing and other industries.

Chemical Type

Imidazoline quaternary ammonium salt.
