COATING COMPOSITION COMPRISING A COMPOUND COMPRISING A SPIRO-ORTHO SILICATE GROUP

摘要

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.
