Techno-Genic Fillers in the Composition of Modern Polymer Paints

The article shows that techno-genic fillers, based on slag of electrometallurgical production, can be used as fillers for water-dispersion paints, based on polymer composition. For these purposes, it is necessary to modify the slag particles, in order to increase its hydrophobic property. The article examines the effect of the mass of the additive of techno-genic filler, based on the modified slag of the electrometallurgical plant, on the properties of the resulting paint. A water-dispersed acrylic composition, containing stearic acid-modified slag of electric steelmaking production as a filler, has been developed. The composition has high uniformity, is more heat-resistant and water-resistant, a high hiding power and viscosity, and corresponds to modern analogues.
