Substitution of Cobalt Driers and Methyl Ethyl Ketoxime
Preface
Due to environmental aspects as well as health concerns it would be desirable if cobalt driers and methyl ethyl
ketoxime as well as hydroquinone could be avoided in coatings.
This project has therefore been undertaken to investigate the possibilities of substituting cobalt driers and methyl
ethyl ketoxime in air-drying coatings. Alternatives for substitution of hydroquinone used as an antioxidant in printing
inks have been investigated as well.
The project is financed by the Danish Environmental Protection Agency and the project partners are: The
Association of Danish Paint and Varnish Industry (FDLF), EnPro and dk-TEKNIK ENERGY &
ENVIRONMENT. Six coating manufactures and two printing ink manufactures have also participated in the
project contributing with products as well as know-how. We thank Akzo Nobel Decorative Coatings A/S; Dyrup
A/S; Beck & Jørgensen A/S; Flügger A/S; Junckers Industrier A/S; Teknos A/S; Akzo Nobel Inks A/S and Sun
Chemical Ink A/S.
Manufacturers of driers and anti-skinning agents have contributed with samples and suggestions for substitution
possibilities. We thank Surface Specialities Nordic A/S, OMG, Borchers GmbH, Sasol Servo BV and Elementis
Specialities for supplying samples and technical know-how.
The technical evaluations were performed by Annette Jensen, Charlotte Pilemand and Eva Wallström – all from
EnPro ApS, whereas the environmental and health assessment has been performed by Pia Brunn Poulsen and Leif
Hoffmann, both dk-TEKNIK ENERGY & ENVIRONMENT. Chabanne Armand and Anette Harboe from the
Association of Danish Paint and Varnish Industry have been project managers.
A steering committee was set up and four meetings have been held during the project period. The steering
committee consisted of:
Kim Petersen Danish Environmental Protection Agency
Chabanne Armand The Association of Danish Paint and Varnish Industry (FDLF)
Anette Harboe The Association of Danish Paint and Varnish Industry (FDLF)
