Metal conditioner descales while preconditioning metal surfaces

PPG Industries’ industrial coatings business has introduced ULTRAX® metal conditioner 257. This near-neutral descaler removes weld scale, light oxide, and other impurities from steel surfaces and preconditions galvanized steel, white metal, aluminum, and other nonferrous metals before pretreatment with zinc-phosphate and other thin films.

The metal conditioner enables descaling and surface activation of welds while preconditioning metal surfaces of parts comprising mixed-metal substrates through a single descaling system.

The product facilitates uniform application of zinc phosphate, which creates a corrosion-resistant barrier on mixed-metal frames, engine cradles, control arms, linkages, and underbody parts exposed to moisture, road salt, and gravel.
