C-202 Multi-functional Surfactant for the degreasing of non-ferrous metals at medium and high temperatures is a surfactant suitable for removing oils from non-ferrous metals such as aluminum, aluminum alloys, zinc, zinc alloys, and magnesium alloys at medium and high temperatures. It possesses excellent washability, compatibility, wetting power, and emulsifying ability, offering strong cleaning performance against various types of oil stains with long-lasting effects. In the washing of heavy oil stains at medium to high temperatures, it can be used in combination with conventional inorganic additives such as sodium hydroxide, sodium carbonate, and trisodium phosphate; a 1% concentration provides an alkali resistance of 20–30% in the presence of sodium hydroxide.
