摘要:
Method for bonding of anchoring bolts in boreholes, in which an anchoring bolt is pushed with a rotary motion into a twin-chamber cartridge, one compartment of which is filled with a polyisocyanate component and the other one with a hydroxyl component, prepolymer from the conversion of polyisocyanates with one or several difunctional polyols of the molecular weight range 800-5000, preferably 1600-3000, being used as polyisocyanate component.
