Abstract
Mixture for the production of acid-resistant sealing materials or acid-resistant impregnating materials based on epoxy resins, resols, hardening catalysts and further customary additives, which are in the form of a cement or impregnating solution and contain, as essential constituents, (A) at least one bifunctional, low-molecular epoxy resin having an epoxide equivalent weight between 87 and 1,000, (B) at least one resol formed from at least one trifunctional phenol and formaldehyde in a molar ratio of 1:1 to 1:3, having a viscosity between 50 and 2,500 mPa.s at 20.degree. C. and having a solids content of at least 50% by weight, and (C) hardening catalysts, cements also containing (D) fillers, in addition, and a process for the preparation of hardening products from the compounds. Thus, for example, cements or impervious, initially porous shaped articles which are resistant to solvents and weak acids and which have a low shrinkage after processing, are obtained.
