Miljøprojekt, 884 – Substitution of cobalt driers and methyl ethyl ketoxime

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)
