Abstract (en)
[origin: WO03074602A2] The invention concerns the use, for improving the life span of moulds made of silicone elastomer crosslinking by polycondensation reaction, of additive capable of stabilizing the silicone elastomer constituting the moulds with respect to materials to be moulded and in particular polyester resins. Said stabilizing agent is based on silica pretreated with a silane. Preferably, it consists of a ground silica-based quartz pretreated with a silane.
