  • the surface obtained is smooth, crack-free and shiny. It also shows that the pot life of the coating composition according to the invention is significantly prolonged. Consequently, the coating composition of the present invention can be processed more easily and effectively.
  • the nonwoven is coated according to the aforementioned example with the composition of the example and dried.
  • Glycidyloxipropylthmethoxysilane and aminopropylthethoxysilane are mixed in a molar ratio of 1: 1. To this mixture gives 1% conc. Nitric acid and 5% ethanol.
  • the coating composition thus obtained is stirred for 1 h and 20 g / m 2 (wet) of the coating composition obtained with a Squeegee applied on the side of the PET nonwoven on which the composition has already been applied. Subsequently, it is dried at 120 ° C. for 30 minutes.
  • the comparative example shows that the resulting coating has a cracked, rough surface.
  • the coated fleece can not be bent without destroying the surface.
  • the pot life of the coating composition of the comparative example is very low for 2 hours, which adversely affects the workability of the coating composition.
