Designed for surface grinding applications, g-25j is non-foaming, transparent, biodegradable, and allows for the rapid settling of residues which eliminates wheel build-up and ensures finer finishes. G-25j is compatible with Brass, Bronze, copper, and ferrous metals, making it an excellent coolant for blanchard grinding. G-25j provides corrosion protection and is ideal for use in machines with magnetic Brass Rings.
