Thermal Decomposition: Do not expose to high temperatures. Thermal decomposition produces methl ethyl ketones, substituted amides and possibly other material. Combustion is expected to produce at least carbon monoxide, carbon dioxide, and oxides of nitrogen. Not compatible with strong acid, oxidant and alkalies.


All personnel handling and/or using MEKO must be familiar with appropriate safety and handling precaution. Before handling always read and follow the safety precaution in Material Safety Data Sheet (MSDS). MEKO is harmful if swallowed or absorbed through the skin.
