The object of the invention, namely developing a method for producing a solvent-free coating material and a solvent-free coating material based on a polymerization product which can be cross-linked with an isocyanate and from which an antimicrobial effect originates, has been solved by providing an amino/hydroxyl functional group binder in a solution tank, by subsequently adding the pigments, fillers and additives to said solution and mixing thereof, by subsequently incorporating an additive in the form of alkali or alkaline earth alumosilicates, represented by the general formula M2/O2-Al2O3-xSiO2-yH2O, to said solution for installing miniaturized water deposits, wherein said alumosilicates are homogenized in this system by way of introducing energy without altering the crystal structure and thus act as a complex anion of ion donators formed by said system, consisting of nanoparticles of metalloids produced by introducing energy and/or organic and inorganic compounds thereof.
