The influence of Co/Sr and Fe/Sr driers on film formation of high solid alkyd coatings.

High solid (HS) alkyd resins with low amount of volatile organic compounds (VOC) were developed as the result of new VOC solvent directive that limit the amount of VOC in decorative paints. Due to specific chemical structure of HS alkyd resins and possible deterioration of some applicative properties the optimal combination of driers is an important subject of research. In our present work we studied the influence of iron (Fe) and cobalt (Co) surface driers with strontium (Sr) through drier on the film formation of HS alkyd coatings.
