FXS also called Polyethyleneglycol octyl (3-sulfopropyl) diether, potassium salt,the Cas No.is 154906-10-2.And the molecular formular is (C₂H₄O)nC₁₁H₂₄O₄S.K. It is yellow to brown liquidor cream.
FXS is an anionic,low foaming surfactant without a cloud point. As a sulfonate FXS is stable againsthydrolysis over a wide pH range.
FXS is used in acid zinc baths as solubiliser for the brightener and as a carrier.FXS increases the cloud point of the bath and leads to bright deposits in the medium and low current densities.Usually YX-15 is
combined with non ionic surfactants.The product is used in barrel and rack plating
