Methyl Ethyl Ketoxime (MEKO) is a highly effective anti-skinning agent widely used in the production of alkyd-based paints and coatings. Its primary function is to prevent the formation of a skin on the surface of paint during storage, which is crucial for maintaining product performance and extending shelf life.

Benefits of Using MEKO:

  • Effectively inhibits skin formation in paints and varnishes
  • Ensures formulation stability during long-term storage
  • Compatible with most alkyd systems
  • Easily evaporates during application and drying

Applications:

  • Alkyd paints and enamels
  • Varnishes and primers
  • Stains and solvent-based decorative coatings

Usage Recommendations:

The typical dosage of MEKO is 0.1–0.3% by total weight of the formulation, depending on the specific paint recipe. It is usually added during the final mixing stage or during packaging.

Packaging and Storage:

Supplied in 180 kg steel drums. Store in a cool, well-ventilated area, away from sources of ignition and direct sunlight.
