Abstract

Baking finishes of low solvent content, which have a viscosity of from 20 to 300 DIN seconds, measured in a DIN cup No. 4, and comprise from 40 to 85% by weight of hydroxyl-containing polymers, from 10 to 55% by weight of amine/formaldehyde resins and from 5 to 35% by weight of polyisocyanates, and may also contain up to 15% by weight of monohydric or dihydric alcohols, up to 35% by weight of solvents, up to 65% by weight of pigments and fillers and up to 3% by weight of crosslinking catalysts. The finishes are particularly suitable for coating automotive components.
