Cobalt and its effects on human health have been increasingly in the focus of legislators and the media for some time now. Worlée (worlee.de) a leading German company in the fields of chemical, natural and cosmetic raw materials, has developed two new products WorléeAdd 2700 and WorléeAdd VP 2560 as an alternative to the cobalt-based siccatives (a drying agent used as a component of paint), which are very limited in use due to their suspected carcinogenic effects.
WorléeAdd 2700 is a cobalt-free catalyst to support the oxidative drying of water-based systems. It causes a fast surface drying and at the same time a good through-drying and hardness development. WorléeAdd 2700 shows low yellowing, good drying stability and is universally applicable and easy to dose.
WorléeAdd VP 2560 is a cobalt-free catalyst for the oxidative drying of conventional alkyd resin paints. It is preferably used in combination with secondary dryers based on calcium and zirconium.
Both new products are based on special manganese complexes and have a comparatively low yellowing tendency due to their low metal content, notes a press communiqué from the company.
