英文名称：Coating powders — Part 12: Determination of compatibility

标准范围
This document specifies a visual method to determine the deterioration of surface quality of the final
coating when mixing two different coating powders. The surface quality will depend on the following
characteristics of the coating powders:
a) the chemical reactivity;
b) the chemical composition;
c) the melt properties.
The onset of the incompatibility in appearance, its nature and its extent will depend greatly on the ratio
in which the powders are mixed. The nature of the incompatibility in surface appearance can manifest
itself in various ways, described in Clause 8.
This test is useful in predicting the possibility of incompatibility arising from mixing different powders
both during the manufacturing process and during the application of the coating powder.
This document concerns only changes in visual aspects of the coating. The mixture series can also be
used for testing properties such as mechanical properties, chemical properties, corrosive properties
and resistance against UV radiation. Further properties can be agreed between interested parties.
