Doped fluid mineral oil free of any chlorinated additives. Excellent spreading of oil film. Good stamping and drawing capacity. The originality of the formulation takes into account the improvement in the operative conditions thus ensuring additional comfort to users. The oiliness, anti-wear and extreme-pressure dopings provide better tool resistance and a very good surface state, which elements contribute to a reduction in production costs. Elimination : degrease by the usual solvents and hot alkaline lyes. The need to protect the environment together with the demand on the part of certain industries have led us to formulate chlorine-free products. This oil achieves performance wholly comparable to those obtained with chlorinated product while at the same time offering the advantage of not causing pollution and of being able to be eliminated at least cost.
