The present invention is directed to a liquid sealant composition based on polysulphide, capable of curing on demand, and the process for preparing same, the liquid sealant composition including: (i) a polysulphide comprising an -SH end group, (ii) a crosslinking agent chosen from ethylenically unsaturated or acetylenically unsaturated compounds, the unsaturated ethylenic or unsaturated acetylenic functions of the crosslinking agent being chemically blocked with a blocking agent, and (iii) optionally, a catalyst. The present invention also relates to a process for coating a substrate with a composition according to the invention, and also to the cured sealant materials formed from this composition. Finally, the invention relates to the use of a liquid sealant composition according to the invention for the construction and/or the maintenance, and more particularly for the adhesive bonding and/or the protection, of vehicles and machines.
