Antiskining Agents

Alkyd paints undergo cross linking polymerization during storage stage forming a skin like polymeric surface at the top of the paint. 

The reason for this polymerization is the trapped oxygen and the catalytic action of cobalt driers.

The skinning as this phenomenon is named can be prevented only by eliminating the cause, in this case the oxygen or the cobalt drier activity. 

This can be achieved by using specific substances that either are free radical scavengers delaying the oxidation process or complexing driers deactivate temporally the cobalt ion. The ion stays free again after application of the paint and evaporation of the complexing agent.


Our company produces the substance methyl ethyl ketoxime as a metal complexing agent and distributes it under the commercial names
