Abstract
A process for the production of an article for the cladding of floors or walls, comprising the steps of, in a mold: a) optionally applying a gel coat layer, based on a first curing polymer resin, on the inside of the mold in order to obtain a coated mold, and b) introducing into the core of the mold or into the core of the coated mold from step a) a filling composition which is based on a second curing polymer resin supplemented with at least one mineral filler, wherein core contains at least 5% wt and at most 20% wt of curing polymer resin, relative to the dry amount of filling composition, and the filling composition contains only one single initiator in a concentration of 0.5% wt to 5.0% wt relative to the amount of curing polymer resin in the filling composition.

A process for the production of an article for the cladding of floors or walls, comprising the steps of in a mold:
- a) optionally applying a gel coat layer, based on a first curing polymer resin, on the inside of the mold in order to obtain a coated mold,
- b) introducing into the core of the mold or into the core of the coated mold from step a) a filling composition which is based on a second curing polymer resin supplemented with at least one mineral filler,
- wherein the core of the article has a thickness of at least 20 mm, the filling composition for the core contains at least 10% wt and at most 20% wt of curing polymer resin, relative to the dry amount of the filling composition, and the filling composition contains methyl ethyl ketone peroxide as the only one single initiator in a concentration of 0.5% wt to 5.0% wt relative to the amount of curing polymer resin in the filling composition,
- whereby the curing reaction of the filling composition is initiated at ambient temperature.
