Cerium octoate

Cerium octoate (CAS 7435-02-1), also marketed as Tib Kat 812, is a cerium-based metal carboxylate used as a drier, catalyst and stabilizer in industrial formulations.

Where is Cerium octoate used?

• Alkyd and air-drying coatings: through-drying drier
• Printing inks: accelerates oxidative drying in oil-based inks
• Polymer and elastomer compounding: crosslinking catalyst and thermal stabilizer
• Mining and metals processing: catalyst precursor in hydrocarbon processing and surface treatment chemistries
• It promotes oxidative crosslinking and polymer curing, reducing process times in coating and resin systems.

Good to know: Improves film hardness and reduces surface wrinkling compared to conventional cobalt-based systems.

Commercial specifications

• Liquid solution, typically in mineral spirits or aliphatic hydrocarbon carriers
• Cerium metal content varies by grade
• Drum and IBC packaging
