Lubricants
Lubricant Additives
Metal-based lubricant additives are commonly used in the formulation of lubricants to enhance performance and impart property improvement in the created lubricants. Primarily beneficial for enhancing anti-wear and anti-friction properties, metal-based additives act to form a protective metal layer on metal substrates, thus reducing metal-to-metal contact.
Metal-Based Lubricant Additives
TIB supplies a select number of metal-based additives with tin, zinc and bismuth chemicals that can be used as lubricant additives. The selection of a specific additive depends on the end-use application, compatibility, and environmental/toxicity concerns. Request a sample of any of our products on their respective pages, or contact us for more information.
Tin-Based Lubricant Additives
Tin-based compounds such as TIB KAT 129 (Stannous Octoate) and TIB KAT 218 (Dibutyltin Dilaurate) Tin-based additives are used in extreme-pressure lubricants. These products contain high active metal contact, include formulation-compatible ligands, and exhibit both a low acid content and low viscosities.
Zinc-Based Lubricant Additives
Zinc-based lubricant additives include TIB KAT 620 BC (Zinc Octoate). Zinc-based types are used in applications where environmental concerns with tins are present and there is a need for low-cost alternatives. Zinc octoate contains a fairly high metal content (20%), a compatible ligand and exhibits both a low acid content and low viscosity.
Bismuth-Based Lubricant Additives
Bismuth-based additives can be used instead of zinc products where zinc use is restricted, such as in the marine and food processing industries. TIB’s bismuth-based lubricant additives include TIB KAT 722 (Bismuth Octoate), TIB KAT 716 and TIB KAT 724 (Bismuth Neodecanoates). The latter bismuth chemical product has a reduced free acid content compared to the catalyst grade of Bismuth Neodecanoate, TIB KAT 716.
