Metalworking Fluid Additives

Dover Chemical offers one of the widest arrays of metalworking additives available anywhere to the compounder/blender. Our core product line of extreme pressure (EP) additives answers the technology requirement needed in modern machining techniques. We are the leader in S, CL, and P additives, as well as offering various alternatives to chlorinated chemistries. Additionally, our boundary lubricant additives, oil-soluble as well as water-soluble, further supplement and enhance our EP additives role and function in the various chip-making and metal deformation operations. Majority of our additives are single components, providing our customer with the flexibility to design their own products. However, Dover Chemical also offers packages and concentrates for those customers that do not wish to stock small quantities of multiple additives to produce their own emulsifier packages or lubricity agents. Finally, supporting our chemistries, and customers, is our laboratory, our direct sales force, and our global distribution network.


Alternatives for CPs in Metalworking Formulations

LONG-CHAIN
Chlorinated Alkanes, C20+
Preferred for drawing and stamping applications, and offer excellent performance in machining of aluminum alloys. Their high viscosity gives additional body and tenacity to lubricant films.

MEDIUM-CHAIN
Chlorinated Alkanes, C14 - C17
They are considered to be the best choice for multi-purpose or general-purpose applications in neat oils, soluble oils, and semi-synthetic fluids. They have good solubility in all base oils, and are the easiest to emulsify into water-based chemistries.
