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.
