Driers are an essential part of all paints based on oxidatively curing resins, which contain unsaturated fatty acids that causes drying and hardening of the paint film by oxidation. Umicore offers a wide choice of metal soaps or carboxylates as driers. Our standard driers are dissolved in aliphatic white spirit D60.
Next to a broad range of single driers we have a variety of mix driers in our portfolio and can prepare mix driers upon specific customer request. Specific driers for high solids systems and alkyd emulsions have been developed.
Today the introduction of REACH has raised uncertainties about the future use of cobalt carboxylates. As a result, the future of alkyd based paints (and all oxidatively curing coatings) has become a point of discussion and concern. Umicore has introduced a new technology that offers an easy alternative to currently used cobalt carboxylates. This unique chemistry, called ECOS ND15, embeds cobalt into a polymer structure, impeding toxicological effects while safeguarding an excellent performance. This cobalt alternative has been widely tested in coatings, inks, unsaturated polyester resins and gelcoats giving excellent application results and proven to be a 1 on 1 replacement for standard cobalt octoate. This technology provides a solution for coatings producers in these turbulent but challenging times.
