Coating composition comprising a compound comprising a spiro-ortho siicate 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 cross-linker, 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 favorable.
