摘要:
Aqueous coating compositions suitable for multi-layer lacquer coatings which contain binders based on water-dilutable polyol compounds in the form of hydroxy-functional poly(meth)acrylates, polyurethanes, polyethers, polyesters and/or polyester-modified poly(meth)acrylates together with crosslinking agents based on aminoplastic resins, phenolic resins, free and/or capped polyisocyanates prepared using poly(C.sub.2 -C.sub.3)alkylene glycol di(C.sub.1 -C.sub.4)alkyl ethers.
摘要:
Clear lacquer coating media suitable for multi-layer coatings, containing self-crosslinking or externally crosslinkable binder vehicles, organic solvents, and in the case of externally-crosslinkable binder vehicles containing one or more crosslinking agents which are different from aldehyde condensation resins, and optionally also containing one or more reactive thinners and customary additives for clear lacquers, with an additional content of A) 0.1 to 3% by weight one or more urea compounds, and B) 0.05 to 10% by weight one or more substances which supply formaldehyde, with respect in each case to the resin solids content which is formed by the binder vehicles, reactive thinners and crosslinking agents.
