Kemu ™ Capstone® (formerly DuPont ™) fluorosurfactant FS-10

Capstone® FS-10 is a colorless to light yellow liquid environmentally friendly anionic fluorosurfactant. Based on the stable structure of its six fluorocarbon molecules, PFOA and PFOS products harmful to the environment will not be decomposed during use, and it has the characteristics of high temperature resistance, strong acid and alkali resistance and strong oxidant resistance.

Capstone® FS-10 is a colorless to light yellow liquid environmentally friendly anionic fluorosurfactant. Based on the stable structure of its six fluorocarbon molecules, PFOA and PFOS products harmful to the environment will not be decomposed during use, and it has the characteristics of high temperature resistance, strong acid and alkali resistance and strong oxidant resistance.

Capstone® FS-10 exhibits excellent wetting ability at very low doses and can reduce the surface tension of aqueous solvents to very low levels. It can be used in water-based and solvent-based systems to provide excellent surface tension reducing properties to enhance wetting, dispersion, leveling and other surface properties.

performance

Capstone® FS-10 can be stable in harsh environments, especially strong acid environment, and its

· Extremely low foaming;

· Meet the requirements of the US Environmental Protection Agency (EPA) on the PFOA voluntary environmental protection plan 2010/2015 project;

· Excellent performance can be exhibited in harsh formulations (such as strong acid, oxidizing, reducing);

· The impurity content is lower than the instrument detection limit *.

Capstone® FS-10 can be used as a film antistatic agent.

Plating bath: improve the wetting performance of the plating solution, form a micro-bubble film on the surface of the plated parts, and suppress the formation of chromic acid mist.

Emulsification: Fluorine monomer emulsification synthesis assistant, such as polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE) emulsion or powder.

Metal processing: cleaning, derusting and pickling. Because it can stably exist and reduce surface tension in harsh environments, especially in strong acid environments, it can reduce processing time, improve efficiency and prevent the plating solution from being carried out.

Application range:

Used as an antistatic agent in films

For the polymerization of fluorinated monomers

For emulsification of fluoropolymer powder

Used as metal surface treatment agent
