MAXUS Q-LS  is a water extendible, general purpose semi-synthetic cutting and grinding fluid formulated to perform exceptionally in a variety of machine operations.

MAXUS Q-LS, when mixed with water, forms a water-thin transparent micro-emulsion that exhibits excellent cooling properties for superior finishes and increased tool life. Q-LS is recommended for use when machining, sawing and grinding ferrous and non ferrous materials where machinability requirements range from mild to moderately severe. The substantial amount of EP additives and high mole weight polymerized esters yield a non-tacky, but significantly enhanced performance in boundary lubrication.  For this reason, the Q-LS is also recommended for use in stamping, tube rolling, drawing and forming operations where the severity of the application is light to moderate. The opaque emulsion is non-foaming, silicon and chlorine free, and is easy to mix in both soft and hard water.

MAXUS Q-LS  remains highly transparent to afford the machine operator full view of the work. The effective biostatic system formulated into the Q-LS  yields a high resistance to microbial degradation and rancidity; this allows for longer coolant life in machine sumps and central coolant systems without special maintenance procedures.  Unlike many solubles and synthetics, the Q-LS remains fluid in and on the surfaces of the machining center allowing slideways, chucks, and tooling to work freely without a hard-to-clean dry or sticky residue.


MAXUS Q-LS incorporates a three part DEA free  rust inhibitor package that provides complete protection for machine tool surfaces and parts in process. MAXUS Q-LS also contains an inhibitor to prevent galvanic corrosion between stacked parts.  This feature makes the Q-LS well suited for the machining of cast iron, copper and its alloys as well as a variety of machine operations on aluminum.
