Locks “VILFER 71TCL” is an odourless evaporating fluid specially engineered for the punching, stamping of aluminium thin sheet metals. The selected solvents of VILFER 71TCL will be evaporated after machining and only leaving very slight negligible residues on the metal parts. Vilfer 71TCL contains special additives which enhance the punching performance and protect aluminium from staining. Vilfer 71TCL does not stain cuprous metals. This product is wildly used in air-condition industries for making aluminium fins in the evaporators and condensers.
