Being a formulator is becoming much more difficult in light of increased regulatory pressures on common raw materials.
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 discuss potential non-toxic alternatives to both of these materials with supporting test results.
Binders that Cure via Oxidation
Drying oils and alkyd resins have many advantages over other binders used in the coatings industry. They are bio-renewable, inexpensive and extremely stable. Alkyds can be used to formulate coatings which have long open times for easier application, yield relatively hard films for kitchens and baths, require minimal surface preparation and provide good stain blocking properties, particularly over water-based stains, inks and m
