Ez-blox® product card banner



Chemical Name: 2-Pentanone Oxime

Function: Blocking Agent, Anti-Skinning Agent, Oxygen Scavenger, Intermediate, Corrosion Inhibitor, Antioxidant

CAS Number: 623-40-5

Labeling Claims: Low Toxicity, High Purity, Water-free

EZ-Blox® optimizes the performance of alkyd-based paint and coating formulations by preventing surface skin formation due to contact with atmospheric oxygen when, between uses, such formulations sit in containers. EZ-Blox® is a breakthrough product that offers a safe, cost-effective replacement for MEKO, typically with equal efficacy and compatibility with other components in such formulations. With EU-REACH certification and low-toxicity, EZ-Blox® is ideal for paints and coatings producers looking to reformulate high-performance alkyd-based systems post ECHA’s reclassification of MEKO as a Carcinogen 1B substance on March 1, 2022.

Advansix Methyl Ethyl Ketoxime (Meko) product card banner


AdvanSix Methyl Ethyl Ketoxime (MEKO)

Chemical Name: Methyl Ethyl Ketone Oxime

Function: Blocking Agent, Anti-Skinning Agent, Oxygen Scavenger, Intermediate, Corrosion Inhibitor, Antioxidant

CAS Number: 96-29-7

Labeling Claims: Low Water Content, High Purity

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.   Adhesive & Sealants Construction adhesives and tapes, labels, and graphic art adhesives. Automotive & Transportation Exterior and body parts, bonding and assembly sealants. Building & Construction Building envelope materials, glazing and window elements, construction sealants and caulks, and other infrastructure applications. Industrial Water treatment applications. Packaging Packaging primer and lacquer coating applications. Paints & Coatings Coatings for automotive OEM, commercial vehicles, vehicle refinish, off road, agricultural and construction equipment, rail, mass transit, coil, and metal, as well as architectural coatings, decorative paints and coatings, roof coatings, and concrete coatings.
