COMPOSITION FOR PRODUCING SEALANT FOR BINDING UNPRIMED SURFACE WITH GLASS AND PLASTIC Russian patent published in 2012 - IPC C09J175/04 C09J183/04 C09J183/08 C09J5/04 C08G18/10 C08G18/12 

FIELD: chemistry.

SUBSTANCE: composition contains one or more urethane prepolymers, having isocyanate residues, one or more compounds which catalyse the reaction of isocyanate residues with water or a compound which contains active hydrogen and one or more alpha-hydrocarbyl silane compounds. The urethane propolymer additionally contains a silane functional group. The composition additionally contains a compound or a polymer, containing silane residues. The composition additionally contains one or more compounds which catalyse silanol condensation. The composition is deposited onto the surface of glass or plastic with a coating or onto the surface of a substrate to obtain a sealant, then brought into contact and the composition is then hardened. The composition is placed between the glass or plastic with coating and the substrate. The sealing composition is used for binding an unprimed surface with a coating, such as a window lintel with glass with a transparent plastic, coated with an abrasive-resistant coating or with glass or plastic with a coating, additionally coated with glass cement, such as ceramic or organic glass cement.

EFFECT: improved composition properties.
