Abstract
Abstract A lubricant containing an adduct of melamine and isocyanuric acid or cyanuric acid is effective for use in high-temperature, low-temperature, or high-pressure atmospheres, or places where black-color producing contamination is not desired, or in metal working, cutting or grinding of metals. The adduct not only functions as a solid lubricant but also as an agent to thicken liquid lubricants such as mineral oil, and it is used as a powder, or as suspended in a lube oil, grease or water, or it can be applied to surfaces subject to wear using a synthetic resin such as vinyl resin or epoxy resin as a binder.
