Semi-Synthetic Coolant
The optimum balance between lubrication and cooling for general machining
Semi-synthetic coolants combine a mineral or ester fraction with surfactants and synthetic additives to offer the best compromise between lubricating and cooling capacity. Typical concentration of 5–8% in water, forming a translucent emulsion. Boron-free, formaldehyde-free, no secondary amines.
