Fluorocarbon surfactant    

Product introduction:
TUW is a carboxylic acid based anionic fluorocarbon surfactant with good solubility in water, strong acid and polar solvents. This product has strong surface activity and can effectively reduce the surface tension of aqueous solution even at very low concentration. It is a good wetting agent. In addition, the product has stable performance in various chemical environments, has certain foaming ability in aqueous and acidic systems, and can show good synergistic effect when mixed with other surfactants. Because of its low pKa value, it can be applied to all pH range aqueous systems. However, because the product contains carboxylic acid groups, it is not suitable to be used in hard water system containing multivalent cations.
TUW complies with relevant environmental protection regulations in Europe, America and the United States, and does not contain perfluorooctanoic acid and perfluorooctanesulfonic acid structures harmful to human body.

Product features:
1. Emulsifying performance (halogenated raw materials): highly effective, recommended for the emulsification of fluorocarbon compounds
2. Wettability: highly effective
3. Washing performance: moderately effective
4. Dispersion performance (halogenated raw materials): highly effective, recommended for the dispersion of fluorocarbon powder
5. Compatibility: it can be used in a wide range of pH values, but it can only be a soft water system with low concentration of multivalent cations

Product application:
Foaming property: there are many initial foam in the aqueous system, the foam has good stability and is stable to oxidants (such as chromic acid, peroxide and other oxidants)
Polymer: it can be used as emulsifier with good performance in the polymerization of fluorocarbon monomer (such as tetrafluoroethylene, vinylidene fluoride, hexafluoropropylene, etc.);
Adhesive: significantly enhance the wetting and leveling performance, improve the permeability and adhesion of the product, and can be compatible with most water-based formulas;
Cleaning agent: it can be effectively used for hair care and hard surface cleaning agent to enhance wetting ability and improve cleaning effect
