Product characteristics: ionic fluoride surfactant, with strong ability to reduce surface tension, excellent chemical stability and thermal stability, excellent biodegradability, low toxicity. It can be used in coating inks, polymer emulsifiers, plastic/rubber processing, cleaning agents and other fields, and can replace directly connected branched-perfluorinated carboxylate (PFOA).

* Emulsification (halogenated raw materials) : highly effective, recommended for the emulsification of fluorocarbons.

* Wettability: Highly effective.

* Washability: medium effective.

* Dispersibility (halogenated raw materials) : highly effective, recommended for the dispersion of fluorocarbon powder.

* Compatibility: Can be used for a wide PH range, but only low concentration polyvalent cation soft water system.

Product use:

* Foamability: in the water-based system, the initial foam is more, the foam stability is good, and the oxidant is stable (such as chromic acid, peroxide and other oxidants).

* Polymer: In the polymerization reaction of fluorocarbon monomers (such as tetrafluoroethylene PTFE, vinylidene fluoride PVDF, etc.) can be used as a good emulsifier.

Adhesive: Significantly enhance wetting and leveling properties, improve product penetration and adhesion, compatible with most water-based formulations.

* Cleaning agent: can be effectively used for hair care and hard surface cleaning agent, enhance wetting ability, improve cleaning effect.
