Anti-skinning Agent — MEKO (Methyl Ethyl Ketoxime) CAS 96-29-7

Description

1. Product Overview
MEKO (Methyl Ethyl Ketoxime, CAS 96-29-7) is a high-performance anti-skinning agent widely used in alkyd-based coatings, paints, inks, and industrial resins. It functions by temporarily blocking oxidative curing during storage, effectively preventing surface film formation (skinning) in oxygen-exposed systems. This ensures extended product usability, improved formulation stability, and reduced material waste. Strategically, MEKO is a critical additive for coatings manufacturers seeking consistent shelf-life performance and production efficiency in competitive industrial markets.

3. Core Industrial Applications
MEKO is primarily used in alkyd resin-based paints, varnishes, and protective coatings to prevent skin formation during storage and transportation. It is extensively applied in architectural coatings, industrial maintenance paints, automotive refinishing systems, and printing inks. In manufacturing environments, it ensures smooth production continuity by reducing wastage from prematurely cured materials. Compared to alternative anti-skinning agents, MEKO delivers superior balance between effectiveness, dosage efficiency, and compatibility with a wide range of solvent-based formulations.
