Unique solutions to the regulatory concerns affecting cobalt and MEKO the Coatings industry

摘要

Formulators who develop coatings based on oxidatively cured (alkyd) binders face major regulatory obstacles for two key ingredients: methyl ethyl ketoxime (MEKO) anti-skinning additive and Cobalt based driers. MEKO's toxicity makes it difficult to meet safe exposure limits due to its volatility. Cobalt carboxylates are being pressured to be classified as carcinogens. In this paper we will discuss potential non-toxic alternatives.
