COMPATIBILITY GUIDE
The following guide is intended for use, only as a guide, regarding compatibility with Ultrachem’s diester and polyolester oils and greases. The information is, to the best of our knowledge, true and accurate, but all recommendations, or suggestions are made without guarantee, since the conditions of use are beyond our control.

* Chemlube® lubricants are formulated to inhibit copper corrosion; however, minimizing exposure to copper will extend the life of any oil.
Cadmium
Zinc
Lead (Certain products contain lead corrosion inhibitors and are acceptable)
We recommend the use of our Omnilube® oils and greases where plastic, paint, or elastomer compatibility may be a problem.
