Abstract
The present disclosure relates to two-component coating material compositions including a paint base component A and a curing component B. The paint base component A includes one or more polyols A1 selected from the group of polyols containing ester groups and which possess a hydroxyl number of 300 to 500 mg KOH/g and have a hydroxyl group functionality of greater than 2. The curing component B includes one or more polyisocyanates B1 having on average 2.4 to 5 NCO groups. The two-component coating material composition possesses a solids content of at least 96 wt %, and the molar ratio of the NCO groups in the curing component B to the acidic hydrogen atoms in the paint base component A is from 1:1.15 to 1:0.95. The disclosure further relates to a method for coating fiber-reinforced plastics and to a method for producing coated fiber-reinforced plastics, and to coating fiber-reinforced plastics.
