"Semiclean L.G.L" is an alkaline cleaning agent effective for removing various types of dirt such as particles, metal residues, abrasives, glass cullet, fingerprints, and organic residues that adhere to the surfaces being cleaned. Due to its low foaming properties, it can be used not only in ultrasonic cleaning machines but also in leaf-type brush cleaning, which tends to produce foam, and jet water flow cleaning. It is suitable for cleaning precision parts such as glass, lenses, quartz, and crystal before and after processing, as well as for degreasing metal parts. 【Properties】 ■ Appearance: Pale yellow transparent liquid ■ Specific gravity (concentrate, 25°C): 1.12 ■ pH (2%, 25°C): 11.7 ■ CODMn (0.1%): 110 mg/L ■ BOD (0.1%): 120 mg/L *For more details, please refer to the PDF document or feel free to contact us.
