This invention relates to the use of resin compositions for chemical anchoring, wherein the resin composition comprises at least: a. a thiol-containing component, and b. a resin containing one or more reactive moieties selected from the group of: i. non-aromatic carbon double bond moieties, and ii. epoxide moieties, and an initiator. Preferably, the resin composition further comprises a diluent, more preferably a reactive diluent. Furthermore, the present invention also relates to the use of a multi-component, preferably a 2-component system of which one component contains a thiol group(s) containing component for chemical anchoring by means of cold curing.
