Properties of Selected Polyurethane Sealants in the Sealing of Cement-based Materials

Popis výsledku v původním jazyce

Since the rise of cement-based building elements, there has been a need to seal these materials. Therefore, this article deals with the sealing of cement-based materials, specifically glass cement. The aim of this work is to find a sealant for sealing this problematic substrate, to verify its suitability and to show that polyurethane sealants are also important in the construction market. The problem of a cement-based substrate lies mainly in the dustiness of its surface, where there are always small dust particles on its surface. The main method for testing these sealants is the tensile test, which checks both the properties of the sealant itself and the contact joint between the sealant and the base material. Tensile test specimens are made of glass-cement plates and three representatives of one-component flexible polyurethane sealants are selected as the sealing material. From the results of the tensile test, it can be concluded that, with the appropriate choice of sealant and primer, problematic c
