Umicore’s VALILUBE and VALIREX lines offer advanced bismuth and zinc-based additives tailored for demanding lubricant and grease applications. Designed to prevent wear and protect against corrosion, these additives deliver reliable performance under extreme pressure (EP) and heavy load conditions.

Our bismuth carboxylates serve as powerful EP and anti-wear agents, forming protective layers on metal surfaces to reduce abrasive wear and prevent seizure. For added protection, VALILUBE/VALIREX Bi, our bismuth-based product, provides robust corrosion inhibition, shielding equipment from damage caused by water, acids and oxygen exposure.

Similarly, VALIREX Zn, our zinc-based naphthenate, offers dependable anti-wear properties. Its efficient anti-rust capabilities protect metal surfaces from degradation and failure.

Umicore’s environmentally friendly naphthenic acid, derived from biodegradable crude oil, is used as a base material for these high-performance metalworking additives, bringing strength and sustainability together.
