DA-8506 and DA-8527 Extreme Pressure 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.

Dover Chemical offers a chlorinated fatty ester and a chlorinated fatty acid which can be used in place of chlorinated paraffins when additional wetting and lubricity properties are desired in metal working applications. They can also be used as substitutes for chlorinated paraffins in lower temperature plasticizing applications.
