Abstract: Solvent-free coating materials and treating agents used as water-based wood or material protective agents containing emulsifiable binding agents, quaternary ammonium compounds and optional additional active agents. The wood or material protective agents are non-flammable and enable a uniform distribution of the binding agent and the quaternary ammonium compounds in the substrates. As a result, the quaternary ammonium compounds function as a dissolving mediator for the binding agents which are dispersed in water without opacifying effects and are used as a biocide. The agents can additionally absorb water-insoluble organic biocides without impairing the homogeneity or stability of the formulation of the homogeneity of the distribution in the substrate.
