Tin derivatives for use as oxygen-activated latent polycondensation catalysts. According to the invention, said tin derivatives have at least one tin-tin bond of the formula (I): R —Y —R wherein R and R which can be the same or different, are selected from hydrogen, and advantageously from the hydrocarbon radicals or together form a divalent radical or a single ring forming-bond; wherein n is at least equal to 2; wherein the Y, which are the same or different, stand for a stannic grouping having the structure (s): R′ and R″, which can be the same or different, are selected from hydrogen and advantageously from the hydrocarbon radicals. Application to paints.
