BASF | Chemetall Applications Specialist Kirk Beaster shared his expertise on March 12, 2024 at Powder Coating Week: Neutral Pickling vs. Acid Pickling -Mineral acids are very corrosive to metal substrates -Acid pickling dissolves iron / metal, that remains in solution as a contaminant -Aluminum, zinc coated substrates and cast iron surfaces may change color or darken -Limitations in a plant installation due to process and worker safety and materials of construction -Acid pickling may be forbidden due to potential for hydrogen embrittlement of steel (safety equipment, armor plating, etc.) -The surface remains very reactive after acid pickling, increasing possibility of more corrosion -Neutral pickles are not corrosive to metal substrates -Neutral pickling doesn't dissolve iron / metal -Aluminum, zinc coated substrates and cast iron surfaces do not darken -Typically, no limitations in a plant installation due to process/worker safety and materials of construction -It’s possible to use most neutral pickling products on products with hydrogen embrittlement restrictions because it does not aggressively attack the base substrate -The surfaces remains inactive and may be protected from oxidation Contact a BASF | Chemetall expert today! https://lnkd.in/eTQs9SiQ #Chemetall #Experts #ExpectMore #BASF #ProcessEfficiency #SustainableSolutions #Automotive #Aerospace #Appliance #MachineShop #CNC #HVAC #Agriculture #HeavyEquipment #Glass #ECoat #EV #ColdForming #Coil #SurfaceTreatment
