IMPROVED COATING SYSTEMS, USE THEREOF FOR COATING COMPONENTS AND COMPONENTS COATED THEREWITH FOR RAIL VEHICLES AND AIRCRAFTS.

摘要

The invention relates to improved coating materials based on RMA systems, which cross-link with the aid of the classic Michael addition. The coating materials comprise at least 15 - 70 wt.-% of one or more CH acidic compounds A, 4 - 40 wt-.% of one or more vinylogous carbonyl compounds B, 0.1 - 15 wt.-% of one or more latent-alkaline catalysts C, up to 10 wt.-% of one or more light stabilizers, up to 20 wt.-% of one or more open-time extenders, and up to 20 wt.-% of one or more pot life extenders, in each case relative to the total amount of the coating material. The invention also relates to the coatings and coating systems produced therefrom, in particular base-coat varnish systems, and to coated components, particularly components for rail vehicles and aircrafts such as railway cars or airplanes.
