ABSTRACT:
The invention relates to a mold for making a composite material part, the mold being coated in a stripping composition. The stripping composition comprises:100 parts by weight of a base ingredient consisting in epoxy polydimethylsiloxane;0.5 to 10 parts by weight of a polymerization agent for polymerizing the base ingredient and constituted by a diaryliodonium salt;not more than 30 parts by weight of an anti-adhesion modulator constituted by a silicone polymer; andnot more than 40 parts by weight of an anti-stick agent making the composition less tacky prior to polymerization and constituted by at least one vinyl ether compound.
