COMPOSITION DÉS ACTIVANTE FACILITANT LE DÉMOULAGE
The present invention relates to an aqueous composition including: at least one retarder; at least one water-soluble film-forming agent; a mold release oil; and a latex that is not alkali-soluble. Said invention further relates to a method for producing deactivated premade parts from a hydraulic binder composition, in particular concrete, including the steps of coating a mold using the composition according to the invention, feeding the fresh hydraulic binder composition, in particular mortar or concrete, into the resulting coated mold, optionally after drying the coating, withdrawing the hardened molded part from the mold, and removing the deactivated film from the surface of the molded part by washing or brushing. Finally, said invention relates to the use of the composition according to the invention for the negative deactivation of a part made of a hydraulic binder material and to facilitate the mold release of said part.
