Electrically conductive floor coatings could not be carried out hitherto on a (meth)acrylate basis since the conductive fillers used such as carbon black, graphite or surfacetreated metal powder prevented curing. According to the invention, therefore, a polymerizable (meth)acrylate system is provided which can be cured at ambient temperatures by a redox system and fulfills the requirements in respect of conductive floor coverings. (Meth)acrylates which can be used for coating, optionally containing other components such as prepolymers, plasticizers, customary additives etc., may be cured with amphorous or spheroidal graphite and/or carbon fibres and/or finely divided metal, whereby other fillers may be added. In particular, amorphous natural graphite, preferably having the particular size 20 to 1000 .mu.m, is suitable. The coatings prepared in this way fulfill the requirements in respect of DIN 51 953. Conductive coatings, particularly floor coatings. |
