Moisture-hardening hot melt adhesive composition (A) comprises at least a silane-functional polyurethane polymer prepolymer compound (I), which is solid in room temperature and exhibits silane group. Moisture-hardening hot melt adhesive composition (A) comprises at least a silane-functional polyurethane polymer prepolymer compound (I) of formula (R 1>-[NH-C(O)-S-R 3>-Si(X) (3-a)(R 2>) a] n), which is solid in room temperature and exhibits silane group. R 1>n-valent organic residue of prepolymer, which is obtained from polyol, polyisocyanate or n-isocyanate group; R 2>1-10C-alkyl; R 3>linear or branched 1-10C-alkylene; X : hydrolysable residue; a : 0-2; and n : 2 or more. Independent claims are included for: (1) a procedure for gluing the substrate S1 with substrate S2 comprising heating (A) at 85-200[deg]C, preferably 120-160[deg]C; applying the heated (A) on a substrate S1; and contacting the applied (A) for one second with substrate S2, where the substrate S2 comprises same or different material as the substrate S1; (2) an article, which was stuck together by gluing procedure; and (3) use of mercaptosilane compound (II) of formula (HS-R 3>-Si(X) (3-a)(R 2>) a) for modifying isocyanate group-containing polyurethane-prepolymer for the improvement of durability (viscosity stability) of a silane functional to be hardened by hot fusion adhesive. |
