Enhanced Durability of Waterborne Alkyd Coatings Utilizing Cobalt-Free High-Performance Catalysts

This is a Past Webinar
Oxidatively-cured materials such as alkyds and other unsaturated oils used for solvent borne enamels and stains are commonly cured with cobalt carboxylate catalysts. While many alkyds are made using sustainable and bio-renewable feedstocks, their high solvent requirements and toxic catalysts used offset many of the environmental benefits. Further, the use of cobalt carboxylates is under pressure due to their probable classification as carcinogens. 

The search for a cobalt substitute has been challenging. A replacement must not only be sustainable but must also be appropriate for all alkyd-based paints (solvent-based, water-based, and high solids), provide equal or superior paint properties when compared to cobalt driers, and be cost-effective. 

Register to attend this webinar to see comparative performance results of high-performance cobalt-free Borchi® OXY-Coat catalysts versus cobalt carboxylates in low VOC waterborne alkyds, and against water borne acrylic coatings. See the significant improvements in performance in many criteria, including corrosion resistance, resistance to UV degradation, abrasion resistance, and more.
