PROCESS FOR PRIMING PLASTIC SUBSTRATES, COATING COMPOSITIONSFOR THIS PURPOSE, AND THE USE THEREOF

摘要

1. Priming of plastic substrates. 2.1. The priming of plastic substrates without adverse effects on the mechanical stability is described. 2.2. A coating composition is used which comprises from to 35% by weight of binders having an OH number of from 40 to 150, prepared from (meth)acrylamides, hydroaxyalkyl (meth)acrylates and copolymerisable, olefinically unsaturated compounds with subsequent modification by means of polyisocyanates, up to 20% by weight of further binders, from 30 to 70% by weight of organic solvents, from 15 to 45% by weight of pigments and/or fillers, from 0 to 15% by weight of additives and from 1 to 30%~ by weight of epoxide- or polyisocyanate-based crosslinking agents. 2.3. Painting of motor vehicle parts made of plastic.
