Methyl Ethyl Ketoxime (MEKO) Main Application
1. This product is an oil based coating antioxidant, used for anti-skinning treatment during
the storage and transportation of a variety of oil based paints such as alkyd paint,
and epoxy ester paint, etc. It can be used as an anti-skinning agent and viscosity stabilizer
for alkyd resin coating. This product is recommended to be added in the amount of 0.1-0.3%
in offset printing ink industry.
2. This product can be used in the synthesis of silicone cross linking agent, curing agent,
and vulcanized single component silicone rubber product at room temperature and also used as isocyanate sealant
3. This product can be used as antioxidant and corrosion inhibitor in industrial boiler or water treatment system.
4. This product can be used as pharmaceutical intermediate for alum and magnesium removal.
5. This product can be used to produce high purity hydroxylamine sulfate and hydroxylamine hydrochloride.
Methyl Ethyl Ketoxime (MEKO) Storage and Transportation
It is flammable, so it should be stored in a shady and cool place to avoid oxidant
and acid. The container should be sealed tightly after each use to avoid damp and oxidation.
Its shelf life is one year. Please handle the transport procedures by ordinary chemical standard.
