Hysol NB is a semi‑synthetic metalworking fluid designed for large central systems and single‑tank machines. It is especially suited for machining cast iron and low‑alloy steel, providing excellent surface finish and stability.
Key benefits include low foam, superior corrosion protection, advanced lubrication, and good wetting properties. For optimal performance, store the product in sealed containers, keep it in a cool dry place away from sunlight, and maintain the recommended water hardness of 100‑700 ppm CaCO₃.
