    摘要: The present invention relates to a two-compartment cartridge which is suitable for securing stay bars in bore holes by means of polyurethane resins and which is destructible by the stay bar, containing a polyisocyanate component on the one hand and a polyol component on the other hand, distinguished by the fact that the polyisocyanate component used is an aromatic polyisocyanate or a mixture of aromatic polyisocyanates, while the polyol component used is a polyol containing tertiary amine nitrogen and having a molecular weight of from about 119 to 3000 or a polyol mixture containing at least one such polyol. The present invention also relates to a process for securing stay bars in bore holes by introducing into the bore hole a two-compartment cartridge which contains components capable of forming a synthetic resin and which is destructible by driving in the stay bar and subsequently driving in the stay bar, distinguished by the fact that a cartridge of the type described above is used as the two-compartment cartridge.
