<p>Humid hardened composition (I) comprises at least a polymer (A) with silane functional group, which is either a polymer (A1) that is obtained by reacting a polyurethane polymer (with an isocyanate group) with an aminosilane (AS1); or a polymer (A2) that is obtained by hydrosilylating a polymer with terminal double bond; at least an aminosilane (AS2) and at least a silane compound (II) (0.6-5 parts by weight, based on 100 parts by weight of (A)). Humid hardened composition (I) comprises at least a polymer (A) with silane functional group, which is either a polymer (A1) that is obtained by reacting a polyurethane polymer (with an isocyanate group) with an aminosilane (AS1); or a polymer (A2) that is obtained by hydrosilylating a polymer with terminal double bond; at least an aminosilane (AS2) and at least a silane compound (II) of formula (X-CH 2-Si(R 1>)-(OR 2>) 2) (0.6-5 parts by weight, based on 100 parts by weight of (A)). R 1> : 18C alkyl, preferably methyl or ethyl; R 2> : 1-5C alkyl, preferably methyl, ethyl or isopropyl; and X : a substituent bonded over a heteroatom. Independent claims are included for: (1) a procedure for binding substrates S1 and S2 comprising applying (A) on the surface of S1, contacting S2 with (A) that is disposed on S1, and hardening (A) by contacting with moisture (where S1 and S2 are same or different from one another); (2) a procedure for sealing comprising applying (A) between S1 and S2 and hardening (A) by contacting with moisture; (3) a bonded article produced by the method; and (4) a sealed article produced by the method.</p> |
