FIELD: chemistry.
SUBSTANCE: invention relates to compositions based on silane-functional polymers, which are suitable for adhesive binding, sealing and coating porous substrates. The composition contains at least one silane-functional polymer, at least one organosilane and at least one organotitanate. The silane-functional polymer is a silane-functional polyurethane polymer or can be obtained through hydrosilylation of polymers, having terminal double bonds. The organosilane contains at least one sulphur atom. The organotitanate has ligands bound to a titanium atom through an oxygen-titanium bond. The ligands are selected from a group consisting of an alkoxy group, a sulphate group, a carboxylate group, a dialkylphosphate group and an acetylacetonate group. Content of the organotitanate in the composition is between 0.1 and 10 wt %. Content of the organosilane in the composition is between 0.1 and 7 wt %. The composition also contains at least one filler, content of which is between 10 and 70 wt %. The composition is used for binding, sealing and coating substrates made from concrete, mortar, brick, tiles, plaster, natural stone such as granite or marble, glass, glass-ceramic, metal or metal alloy, wood, plastic and lacquer.
EFFECT: obtained article, which is bound, sealed or coated using the composition, is a building structure, more specifically a building or civil construction structure; the composition guarantees efficient adhesion to a substrate even after storage in the presence of water.
