AdvanSix Methyl Ethyl Ketoxime (MEKO)

Sold by AdvanSix
Supplier:  AdvanSix

Methyl ethyl ketoxime (MEKO) is a high-efficiency anti-skinning agent used for air-drying paints, inks and coatings. It can also be used to improve the shelf life of silicone adhesives and sealants and the functionality of polyurethane coatings. MEKO meets the most stringent standards for low moisture and high assay.

As a safe, cost-effective alternative to MEKO, AdvanSix also offers EZ-Blox®, which provides low risk of exposure and an improved toxicology profile. EZ-Blox® does not require costly reformulation or additional research and development, and independent research shows it is safe as a versatile intermediate for use in Adhesives & Sealants, Automotive & Transportation, Building & Construction, Industrial, Packaging, and Paints & Coatings applications.
