This document specifies the method for determining the fluorine content in cross-linked fluororesin coating base materials using ion chromatography. This document applies to two-component or one-component fluorocarbon topcoat with fluororesin containing reactive functional groups as the main film-forming substance specified in HG/T3792. It is applicable to but not limited to building exterior walls, concrete surfaces and metal Use topcoat on the surface; the fluorine content test of fluororesin raw materials can also refer to this document.
