Shearglide NPC Series Metal Working Fluids are designed to provide excellent performance without the use of Chlorine and Phosphorus. They employ a special EP additive combined with active and inactive sulfurized lubricity agents to produce a full line of cutting oil products. The unique EP agent in Shearglide NPC Series Metal Working Fluids functions by physically plating on the work surface during metal forming. It creates a film of low shear strength and high melting point. This chemical inert reaction with metal surfaces permits higher turning speeds and feeds. By contrast, chlorinated waxes function by reacting with metal surfaces to produce films of chlorides. These chlorides contribute to fluid degradation, and interfere with rust inhibitors. In addition, chlorine adds to ecological problems and disposal costs.
