Definitions
- the invention relates to a method for multi-layer painting, in particular refinishing of substrates with a filler layer and a top coat layer, which is used in particular in the field of vehicle and vehicle parts painting.
- Multilayer vehicle refinish coatings generally consist of a filler layer applied to optionally precoated substrates and a top coat of a color and / or effect basecoat layer and a transparent clearcoat layer. However, it can also be a top coat made from a pigmented single-layer top coat.
- aqueous or so-called high-solid coating agents have already been developed for almost all paint layers.
- two-component water-based paints based on hydroxy-functional binders and polyisocyanate hardeners and on the basis of epoxy / polyamine systems are known.
- the coatings obtained with these varnishes do not yet correspond to the level of properties of conventional solvent-based fillers or primers in several respects.
- the sandability of water fillers is still insufficient, and there are problems to ensure bubble-free application at higher layer thicknesses.
- an extended drying time must generally be accepted, which impairs the effectiveness, for example, in a paint shop.
