AQUEOUS COATING COMPOSITIONS AND PROCESS FOR THE PRODUCTION OF COATING LAYERS |
摘要 |
Aqueous coating compositions with a resin solids consisting of 60 to 80 wt. % of binder solids and 20 to 40 wt. % of cross-linker solids, the binder solids consisting of 20 to 100 wt. % of binder C and 0 to 80 wt. % of one or more further binders and the cross-linker solids consisting of 80 to 100 wt. % of one or more aminoplast resins and 0 to 20 wt. % of one or more further cross-linkers, the sum of the respective wt. % equalling 100 wt. % and the binder C being produced by reacting a polyisocyanate A partially blocked by one or more monoalcohols A2 and having a content of free isocyanate groups of 0.5 to 10 wt. % with a resin B comprising a hydroxyl number of 50 to 250 mg KOH/g and a carboxyl number of 10 to 50 mg KOH/g at a molar ratio of hydroxyl groups of B to free isocyanate groups of A of at least 2:1. |
