PROBLEM TO BE SOLVED: To provide a composition useful as an adhesive for bonding glass to a vehicle and a building, having moderate press flow viscosity and excellent in curing speed and shock resistance of a cured product.SOLUTION: There is provided the composition containing a) one or more isocyanate functional polyether-based prepolymer having an average polydispersive index of about 2.5 or less calculated by GPC (Gel Permeation Chromatography) at an Mp of over 1,000 and 1.2 to 2.2% of free isocyanate, b) less than 15 wt.% of one or more plasticizer, c) one or more catalyst for a reaction of an isocyanate component and an isocyanate reactive group, d) one or more filler in such a sufficient amount that the composition shows a predetermined press flow viscosity, i.e. about 8 g/min. or more, the composition exhibiting 1.6 MPa or more of a peak strength and about 2.5 J or more of energy absorption at a high speed impact test at 4 m/s according to DIN EN1465 at 30 minutes after being applied. |
