Definition - What does Anti-Skinning Agent mean?
An anti-skinning agent is any corrosion coating maintenance measure taken to prevent the formation of insoluble skins on a coating's surface due to polymerization or oxidation reactions.
Corrosionpedia explains Anti-Skinning Agent
Anti-skinning agents are typically added to coatings that are stored for significant periods of time while still in a container. Skins are most likely to form when large quantities of stored coatings sit idle and stagnate.
