Potassium Hydroxide 50% (KOH, CAS 1310-58-3) is a clear, colorless, strongly caustic solution with a specific gravity of about 1.50. It stays liquid at lower temperatures than 50% caustic soda, which makes it easier to store outdoors in cold climates. Liquid KOH is used in detergent and soap making, potassium chemicals, de-icers, oil and gas processing, metal cleaning and pH control. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
