Anti-skinning agents

Anti-skinning agents are added to prevent unintended skinning on paints and printing inks. The need for preventing skin formation might range from preventing in-can skinning during storage in closed container to preventing the ink from drying in the press duct. Methyl Ethyl ketoxime (MEKO) anti-skinning agents are commonly used to prevent alkyd coating surfaces from forming a film called skin, particularly when driers that are reactive to oxygen are used in these paints.
