Coatings based on oxidatively cured alkyd resins have relied on conventional metal carboxylate driers for decades. Today, the most used metal carboxylate is cobalt. Although cobalt and metal carboxylate surface driers are efficient in curing, their utilization brings many performance and regulatory drawbacks. These systems may encounter yellowing, marginal dry time improvement, and wrinkling at high film thicknesses. Solvent borne long oil and high solid systems also present their own challenges in which formulators typically need a large quantity of conventional driers to find adequate cure. Most importantly, there is a global initiative to remove cobalt carboxylate driers from all paint formulations.
This presentation will show the benefits that organometal complex driers bring to alkyd coatings. As well as introduce a new novel drier technology which fills the gap to improve cure in the most challenging solvent borne systems. These organometal complexes not only improve dry time and paint performance, but also improve the labeling of the paint system by utilizing cobalt- free, VOC-free (in waterborne coatings), and APEO-free technology.
