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) -A-CH—SiXYZ (I), in which A is a divalent bonding group, X, Y, Z are, mutually independently, are Cto Calkyl, Cto Calkoxy, or Cto Cacyloxy groups, where at least one of the substituents is a Cto Calkoxy or Cto Cacyloxy 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. 1. A curable agent containing two components (1) and (2) that are not in mutual contact , wherein {'br': None, 'sub': n', '2, '-A-CH—SiXYZ\u2003\u2003(I),'}, 'component (1) contains at least one polymer having at least one terminal group of the general formula (I)'}in whichA is a divalent bonding group containing at least one heteroatom,{'sub': 1', '8', '1', '8', '1', '8', '1', '8', '1', '8, 'X, Y, Z are substituents on the Si atom and, mutually independently, are Cto Calkyl, Cto Calkoxy, or Cto Cacyloxy residues, where at least one of the substituents is a Cto Calkoxy or Cto Cacyloxy residue, and'} 'component (2) contains at least water and at least one silanol condensation catalyst.', 'n is 0 or 1; and'}2. The curable agent according to claim 1 , wherein the divalent bonding group A in formula (I) is a carbamate group or urea group.3. The curable agent according to claim 1 , wherein X claim 1 , Y claim 1 , Z in formula (I) are claim 1 , mutually independently in each case claim 1 , a methyl claim 1 , an ethyl claim 1 , a methoxy claim 1 , or an ethoxy residue.4. The curable agent according to claim 1 , ...
