## Abstract

The invention relates to a water-based coating composition with the following components: 21-51% water, 4-13% diatomite C110 (flux calcined diatomaceous earth, commercially available under CELITE), 2-6% calcined alumina, 0.3-2% hexylene glycol, 16-47% elastomeric acrylic resin, 0.7-3% acrylic thickener, and 0.7-3% ammonium hydroxide. Preferably, the composition also includes optionally the following components in order to provide the insulating, corrosion-inhibiting, self-extinguishing, impermeable, epoxy and ecological properties: 2-6% titanium dioxide, 4-13% precipitated calcium carbonate, 2-6% dibutyl phthalate, 0.3-2% TEXANOL (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate), 0.3-2% fungicide, and 0.3-2% anti-foaming agent. By means of these ranges, a variety of applications can be covered for which the composition of an insulating, corrosion-inhibiting, self-extinguishing, impermeable, epoxy and ecological coating was developed.
