MEKO, short for methyl ethyl ketoxime, plays a crucial role in the formulation of paints and coatings. Its primary function is as an additive, often used as a drying agent or inhibitor in various coatings and paints. In this blog we look at of its role and significance:
MEKO as an Anti-skinning Agent:
MEKO is widely recognised for its ability to inhibit skinning in paints and coatings. Skinning refers to the formation of a film or a layer on the surface of the paint when exposed to air. This phenomenon can impair the quality of the coating and make it challenging to use the paint effectively. MEKO serves as an anti-skinning agent by preventing this surface film formation, thereby maintaining the usability and quality of the paint.
In addition to its anti-skinning properties, MEKO also acts as a drying agent in certain coatings. It facilitates the oxidation and polymerisation processes in the paint film, accelerating the drying time. This feature is particularly valuable in industries where quick drying times are essential to increase efficiency in production processes.
MEKO serves as an oxidation inhibitor by preventing or slowing down the oxidative degradation of the paint or coating. Oxidation can lead to the formation of undesired compounds, colour changes, or even reduced durability of the coating. MEKO helps mitigate these effects by inhibiting the oxidation reactions, thereby enhancing the longevity and stability of the paint.
Compatibility and Usage:
MEKO is compatible with various types of coatings, including alkyd, epoxy, and polyurethane-based systems. Its versatility allows it to be incorporated into solvent-based as well as water-based coatings.
MEKO plays a multifaceted role in the formulation of paints and coatings, primarily as an anti-skinning agent, drying accelerator, and oxidation inhibitor. Its versatility and compatibility with various coating systems make it a valuable additive, contributing to the performance, usability, and longevity of paints and coatings across diverse industrial applications.
