Protective varnish formulation, as a climatic and/or moisture protection coat on electrical and/or electronic assemblies or components, comprises at least a cellulose ester or at least a cyclic rubber obtained from at least a regenerating raw material, where the protective varnish formulation is based on at least one of the component obtained from at least a regenerating raw material. Independent claims are included for: (1) a moisture protective coating comprises the protective varnish formulation; and (2) an electrical and/or electronic assembly or component exhibits a complete or partial climatic and/or moisture protection coat from a protective varnish. Für eine Schutzlackformulierung, die als Klima- und/oder Feuchteschutzüberzug auf elektrische und/oder elektronische Baugruppen oder Bauelemente aufbringbar ist, soll eine Lösung geschaffen werden, mit der ein Ressourcen schonender Klima- und Feuchteschutz für elektrische und/oder elektronische Bauelemente und/oder Baugruppen herstellbar ist. Dies wird dadurch erreicht, dass die Schutzlackformulierung zumindest im Wesentlichen auf zumindest einer aus mindestens einem nachwachsenden Rohstoff erhaltenen Komponente basiert und mindestens einen aus mindestens einem nachwachsenden Rohstoff erhaltenen Celluloseester oder mindestens einen aus mindestens einem nachwachsenden Rohstoff erhaltenen Cyclokautschuk umfasst.
