Chemours (formerly DuPont) surfactant Capstone ® Overview of FS-10 environmentally friendly non-ionic fluorinated surfactant:
Capstone ® FS-10 Fluorine Surfactant by Chemours ™ (Originally DuPont) ™） Developed and produced, it is an environmentally friendly anionic fluorinated surfactant in a colorless to pale yellow liquid form. Based on the stable structure of its six fluorocarbon molecules, PFOA and PFOS products that are harmful to the environment will not decompose during use, and it has the characteristics of high temperature resistance, strong acid and alkali resistance, and strong oxidant resistance.
Capstone ® FS-10 fluorinated surfactant exhibits excellent wetting ability at very low doses, reducing the surface tension of aqueous solvents to very low levels. Can be used in aqueous and solvent based systems to provide excellent performance in reducing surface tension, thereby enhancing wetting, dispersion, leveling, and other surface properties.
Capstone ® FS-10 Fluorine Surfactant Performance:
Capstone® FS-10 Fluorine surfactants can exist stably in harsh environments, especially in strong acid environments, and their
· Extremely low foaming;
· Meets the requirements of the US Environmental Protection Agency (EPA) for the PFOA Voluntary Environmental Protection Program 2010/2015 project;
· Excellent performance can be demonstrated in harsh formulations such as strong acids, oxidizing properties, and reducing properties;
· The impurity content is below the detection limit of the instrument.
