FIELD: chemistry.
SUBSTANCE: hardening composition is obtained by selecting (i) a chemically active carrier from polyesters, epoxides and alkoxylates which do not contain styrene, or (ii) a chemically inactive carrier from phthalate and benzoate plasticisers, and short-chain saturated polyesters. Further, a peroxide catalyst is selected from ketone peroxides, cumyl hydroperoxides, dibenzoyl peroxides, peroxy esters, perox yketals and peroxy dicarbonates. Thickened and volumising agent - microspheres are then added and the carrier, catalyst and microspheres are mixed. Using said thickened hardening composition, a two-component thermo-reactive polyester resin is obtained.
EFFECT: invention enables to obtain hardening compositions which, at room temperature, remain stable for more than one year.
