Problems solved by technology

[0003] Corrosion-resistant and weather-resistant coil coating surface conditioning and decoration The best known state of the art is the so-called PVDF (polyvinylidene fluoride) lacquer layer, but this has significant design-technical disadvantages, Because only the mid-gloss range is achievable (25-30 gloss units, performed at 60° in the Gardner test)

Abstract

The invention relates to a semifinished product comprising a high-quality, weather-resistant coating, as well as to a method for manufacturing same and to the use thereof.

Description

technical field [0001] The invention relates to semi-finished products with high-quality and weather-resistant coatings and very good corrosion protection. Here, the basis lies in the combination of "long-term durability with aesthetic appearance" and the classic standard of effective corrosion protection. Background technique [0002] Weather-induced loads are unavoidable in materials for exterior applications. Such loads are caused especially by the ultraviolet fraction of sunlight, by very different corrosion mechanisms, by cleaning processes, by media attached by the wind (sand, dust) or in special cases of application by other corresponding loads. Unprotected or insufficiently surface-conditioned materials especially lose their quality or durability. Furthermore, materials based on metallic substrates are also subject to significant corrosion potentials, whereby the corrosion protection aspects of the coatings according to the invention are of particular interest. ...
