The polymer sand composite consists of: Filler. Clean screened sand with a particle size of up to 3 mm is considered one of the best materials. It should not contain clay and dust-like inclusions, which reduce the strength properties of finished products. A negative factor affecting the quality of the mixture is the increased humidity of the filler: evaporation during the preparation of the mixture and the formation of finished products leads to the formation of voids. It is possible to use other mineral fillers: granite screenings, quartzite, basalt, glass, porcelain, broken ceramic bricks. Pigment. The technology for the production of polymer sand products involves through coloring, so pigments are introduced into the mixture. It is possible to use any mineral and organic dyes. Most popular: chromium oxide, titanium dioxide, red lead, cobalt blue. The main selection criteria: availability, price and UV resistance. binder.
