UL Prospector


Dover Chemical Corporation - Lubricant Additives makes their documentation available in the regions indicated below:

MAYCO® BASE 4220 is a sulfurized methyl ester designed to be used in products where low viscosity, excellent base oil (especially highly refined paraffinic) stability, and high wetting characteristics are key. It possesses relatively low odor for such a highly sulfurized additive and the very low viscosity makes blending the additive into base oil an easy task. MAYCO® BASE 4220 can be utilized as a performance booster sump-side, as it will readily mix with the currently used product in the system, if applied at a point of even mild agitation or circulation.
