Definitions

  • the invention relates to the use of additive combinations which are suitable for avoiding undesirable skin formation in oxidatively drying lacquer systems and which

It concerns new additives that are able to skin formation in the above. To delay paint systems. Additive systems of this type are also able to improve through-drying and flow of the coating systems.
  • Oils and binders which are caused by the action of oxygen (preferably atmospheric oxygen) by adding dry substances, e.g. B. metal carboxylates of transition metals, oxidatively crosslinking and thereby form a solid binder film can in the

  • film hardnesses obtained should not be adversely affected and the products should not have any adverse toxicological properties.
  • Another object of the present application was the production of anti-skinning agents that can be used in many different oxidatively drying paints can be incorporated and, due to their physical properties, are unproblematic and can be used in a variety of formulations.
