PPG Industries' industrial coatings business has introduced Ultrax metal conditioner 257.

The conditioner is a near-neutral descaler solution that removes weld scale, light oxide and other impurities from steel surfaces and preconditions galvanised steel, white metal, aluminium and other non-ferrous metals prior to pretreatment with zinc-phosphate and other thin-film pretreatments.

PPG says Ultrax metal conditioner 257 is a "significant technical breakthrough" as it enables descaling and surface activation of welds while pre-conditioning metal surfaces of parts comprised of mixed-metal substrates through a single descaling system.

Multi-metal components are increasingly in demand among automakers because their lighter weight promotes greater fuel efficiency and improved corrosion resistance.
