Abstract: The invention aims to improve temperature resistance for a curable composition based on a silyl-terminated polymer. This is achieved by using a combination of at least two phenolic compounds, of which one is free of thioether groups, while the other contains at least one thioether group in at least one alkyl side chain. The invention further relates to the use of the curable composition as an adhesive, sealant and/or coating substance and to the use of the combination of phenolic compounds to increase the temperature stability in curable compositions.

Abstract: In the context of a curable agent based on at least one silyl-terminated polymer, the adhesion spectrum for bonding plastics, and the speed at which adhesion builds up, are to be improved. This is achieved by making available a curable agent containing two components (1) and (2) that are not in mutual contact, where component (1) contains at least one polymer having at least one terminal group of formula (I) -An-CH2—SiXYZ (I), in which A is a divalent bonding group, X, Y, Z are, mutually independently, are C1 to C8 alkyl, C1 to C8 alkoxy, or C1 to C8 acyloxy groups, where at least one of the substituents is a C1 to C8 alkoxy or C1 to C8 acyloxy group, and n is 0 or 1; and component (2) contains at least water and at least one silanol condensation catalyst. A further subject of the present invention is the use of the agent according to the present invention as an adhesive and/or sealant.
