ABSTRACT:
A flux for use in a hot dip galvanization process has an acidic component so that the flux has a pH of about 1.5 or less. The flux also includes an alkali metal chloride and a nonionic surfactant containing polyoxyethylenated straight-chain alcohols with a hydrophile-lipophile balance (HLB) of less than 11. Depending on the particular application, the flux also includes other components, such as ferric chloride, an inhibitor containing an amino derivative and bismuth oxide.
