Methyl ethyl ketoxime

Methyl ethyl ketoxime (CAS 96-29-7), also known as MEKO or 2-butanone oxime, is an oxime compound used as a skinning inhibitor and anti-skinning agent in solvent-based coatings and alkyd systems.

Where is Methyl ethyl ketoxime used?

• Coatings and alkyd paints: blocks metal drier activity at low concentrations
• Paints, varnishes and printing inks: prevents premature surface oxidation during storage and application
• Printing inks: extends shelf life in oxidatively drying systems without compromising cure performance
• Silicone sealants and adhesives: crosslinker and release agent
• Specialty chemical synthesis: catalyst precursor and intermediate
• In moisture-cure systems it enables controlled adhesion profiles.

Commercial specifications

• Purity typically 99% or above
• Technical grade predominant commercial specification
• Clear liquid in drums and IBC containers
• Stable when stored under proper conditions in original sealed containers away from heat
