AdvanSix Methyl Ethyl Ketoxime (MEKO)

Producer:  AdvanSix
AdvanSix methyl ethyl ketoxime (MEKO) is a high-efficiency anti-skinning agent used for air-drying paints, inks, and coatings. It is used to produce RTV neutral-cure silicone sealants, coatings and adhesives that possess long shelf-life and good adhesion. MEKO is also used as a blocking agent for isocyanate cross-linkers and urethane prepolymers in one-part polyurethane coatings and adhesives. It is produced to meet the low moisture and high assay standards formulators require. EZ-Blox® anti-skinning agent can be used as a cost-effective drop-in replacement for MEKO in jurisdictions where regulatory requirements differ.
