Resumen:
In many areas (e. g. car manufacture, industrial coatings, coatings for plastics) the coating materials used are adapted to the specific application equipment and settings of the particular user. A coating material is, therefore, to be understood as a semi-manufactured product that only achieves its final form in combination with the specific application conditions. The adaptation to the application conditions is therefore decisive for the quality of the coated product. The test methods specified in ISO 28199 are based on studies by a Working Group of the European Council for Automotive R&D (EUCAR). They may be used for evaluation of coating materials in research, development and production with regard to their suitability and safety for industrial processes, and error analysis. The properties to be evaluated for coating materials and coatings depend on the film thickness, so a coating system of increasing or constant thickness is applied to one or more test panels under defined conditions depending on the surface properties to be tested. The following characteristics are measured (in this part of ISO 28199): - film thickness in accordance with ISO 2808; - surface texture; - colour in accordance with ISO 18314-1; - mottling; - gloss in accordance with ISO 2813. In combination with visual assessment, the following properties are determined: - colour stability/colour evaluation, process hiding power, re-dissolving, overspray absorption, wetting, surface texture and mottling (ISO 28199-2). The surface texture can be measured both independently of the film thickness and at constant film thickness. Mottling is preferably measured at constant film thickness; - tendency to sagging, formation of bubbles, pinholing and hiding power (ISO 28199 3). This document defines terms relating to the evaluation of coating materials in research, development and production with regard to their suitability and safety for industrial processes and error analysis as well as methods for the preparation of test panels and the subsequent measurement of film thickness, colour, surface texture and other measurable surface properties.
