ABSTRACT:
The anchoring cartridge for anchoring a fastening element in a drilled hole has two chambers. One chamber contains from 1.0 to 10% of a hardener component dissolved in a mixture of styrene and an unaccelerated radical-curing resin and the other chamber contains an accelerator mixed with another mixture of styrene and unaccelerated radical-curing resin. By including unaccererated radical-curing resin in both chambers a homogeneous curing of the components is ensured.
