This standard specifies the product classification, requirements, test methods, inspection rules, marking, packaging and storage of cross-linked fluororesin coating products. This standard is applicable to two-component films that use fluororesin containing reactive functional groups as the main film-forming substance, add pigments and fillers (not added to varnish), solvents, auxiliaries and other auxiliary materials as the main agent, and use aliphatic polyisocyanate resin as the assimilation agent. Room temperature curing topcoat for building exterior walls, concrete surfaces and metal surfaces. This standard also applies to fluororesins containing reactive functional groups as the main film-forming substance, amino resins or blocked aliphatic polyisocyanate resins as cross-linking agents, and the addition of pigments and fillers (not added to varnishes), solvents, additives, etc. A one-component baking assimilable topcoat for metal surfaces made of auxiliary materials. Cross-linked fluororesin coatings used on other substrate surfaces can also refer to this standard.
