The invention pertains to a coating composition comprising a compound comprising at least one spiro-ortho silicate group and a hydroxyl-reactive crosslinker, to a process for curing the composition, and to the use of the composition. The coating composition of the current invention can be formulated to a coating composition having a low content of volatile organic solvents, is curable at a temperature as low as 5 °C, and the cured coating composition of the current invention is essentially free of unreacted low-molecular weight blocking agents. Further, the pot life: drying time ratio of coating compositions according to the invention is particularly favourable. L'invention concerne une composition de revêtement comprenant un composé renfermant au moins un groupe silicate spiro-ortho et un agent de réticulation réactif avec des groupes hydroxyl, un procédé de durcissement de la composition et l'utilisation de celle-ci. La composition de revêtement selon l'invention peut être formulée en une composition de revêtement possédant une faible teneur en solvants organiques volatils, durcissable à une température aussi basse que 5 DEG C et sensiblement exempte d'agents de blocage de faible poids moléculaire n'ayant pas réagis. En ce qui concerne le délai d'utilisation: le temps de séchage de la composition de revêtement selon l'invention est spécialement favorable.
