Chemical resistance

The chemical resistance of a powder coating depends among other things on its formulation. Chemical resistance requirements therefore must be considered according to processing conditions and final use of the finished product. This is best already established during the product specification process. Agreement between all parties involved must be reached about the chemical resistance test method, which may be performed in accordance with EN ISO 2812-1 "Lacquers and Paint Products. Test Methods for Surface Resistance to Liquids”. It is necessary to also have a common understanding of the requirements for such chemical resistance, such as test duration, test method, reactive time and concentration of the test media.
