Abstract:
1. A method for the production of solid materials with an air content of ≦16.0 volume %, based on the total volume of the solid materials, comprising applying to a substrate a hydraulically setting coating agent containing cationically stabilized polymers comprising one or more polymeric protective colloids, which contain cationic charges, and one or more polymers based on vinyl acetate, vinyl propionate, vinyl butyrate, vinyl 2-ethylhexanoate , vinyl laurate, 1-methylvinyl acetate, vinyl pivalate, vinyl esters of alpha-branched monocarboxylic acids with 9 to 13 C atoms, methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, propyl acrylate, propyl methacrylate, n-butyl acrylate, n-butyl methacrylate, 2-ethylhexyl acrylate, norbornyl acrylate, ethylene, propylene, 1, 3-butadiene, styrene, vinyl toluene or vinyl chloride; wherein the one or more polymers are stabilized with a stabilizer consisting of one or more cationic protective colloids and optionally nonionic protective colloids and/or nonionic emulsifiers; said applying comprising spray methods using compressed air with an air consumption factor from 10 to 100.
