TWO-COMPONENT REACTION RESIN SYSTEM

摘要

The invention relates to a reaction resin system consisting of a resin component and a hardener component, both components being separated prior to treatment. The resin component A contains a polysiloxane, an epoxy functional component and a hydraulic binding agent and the hardener component B comprises polyamine and water. The ratio of water to the hydraulic binding agent in the reaction resin system is = 0,5. For said system in which the epoxide equivalent weight is between 130 and 2 000, the ratio of polysiloxane to the epoxy functional components is 1 : 5 to 95 and the ratio of epoxy equivalent weight to the polyequivalent weight should be 1 : 0,5 to 1,5. It is suggested that the ratio of water to the hydraulic binding agent, which is = 0,4, should be adjusted. Primarily, the use of said reaction resin system is as coloured joint mortar, the advantages are such that it has an improved cleaning property, a reduced tendency to get dirty, an increased resistance to chemical and climatic influences and a visibly higher colour stability.
