    摘要: Previous coating materials lead to the formation of bubbles at high layer thickness and when drying by heating. The new coating materials are intended to be bubble-free when dried at higher layer thicknesses.Aside from pigments and/or extenders, the coating material contains solvents and, if necessary, conventional paint auxiliaries in a vehicle mixture, comprising essentially 60-75% by weight of a hydroxy-functional copolymer, 1-5% by weight of an ester-soluble nitrocellulose and 25-35% by weight of difunctional or multifunctional polyisocyanate. It can be cured without forming bubbles even when applied in thick layers.Use as primer and filler.
