Abstract
A process for anchoring a fastener in a base comprising introducing a bore hole in the base a destructible multiple chamber cartridge containing a reactive set for producing a synthetic resin body. The reactive set contains 3-60 parts by weight of a vinyl ester epoxy resin, 28-45 parts by weight of styrene and/or methyl methacrylate, 63-3 parts by weight of an unsaturated polyester resin which is not an ester of a polyepoxide with an ethylenically unsaturated monocarboxylic acid, 10-0.1 parts by weight of an epoxy resin which is not an ester of a polyepoxide with an ethylenically unsaturated monocarboxylic acid, 0.4-1.2 parts by weight of an organic peroxide hardener component, 40-55 parts by weight filler, accelerators, and polymerization inhibitors. The organic peroxide and resin components are in separate chambers. The cartridge is driven into the borehole so that the cartridge is destroyed and the organic peroxide is mixed with the resin components whereby the resin is cured.
