Butanone Oxime, identifiable by CAS 96-29-7, functions as an essential anti-skinning agent used primarily to prevent surface film formation in alkyd-based paints and varnishes during storage. Chemically defined as Methyl Ethyl Ketoxime , this clear, colorless liquid serves as an oxygen scavenger that temporarily inhibits oxidative cross-linking in air-drying coating systems. The substance, often referred to as MEKO or 2-Butanone Oxime in formulation protocols, acts as a volatile complexing agent for metal driers, evaporating upon application to allow normal curing. We facilitate bulk supply of this coating additive with competitive factory pricing, capable of meeting customized specifications for purity and color, backed by comprehensive MSDS, TDS, COA documentation.

FAQ - Technical & Supply Chain
-
Q:
Is Butanone Oxime chemically synonymous with MEKO?
A: Yes, Butanone Oxime and MEKO refer to the same organic compound identified by CAS 96-29-7, widely recognized as the standard anti-skinning additive in the paint industry. -
Q:
Is this additive suitable for preventing skinning in alkyd paints?
A: Butanone Oxime is typically applied as an anti-skinning agent in oxidative drying systems, where it complexes with cobalt driers to prevent premature surface drying in the can without affecting the final film properties.
