Scope

Scope: This document specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for inorganic coatings used in interior construction. This document applies to liquid inorganic coatings that are mainly made from inorganic materials, with the addition of pigments, fillers, and various additives. These coatings are applied by brush, spray, or roller coating methods to form a smooth coating on the interior walls of buildings. Main technical content: Based on JG/T 26-2002 "External Wall Inorganic Architectural Coatings", GB/T 9755-2014 "Synthetic Resin Emulsion External Wall Coatings", and GB/T 9756-2018 "Synthetic Resin Emulsion Interior Wall Coatings", the standard proposes more accurate methods for testing polymer organic compounds, emphasizes the characteristics of inorganic materials, effectively distinguishes inorganic coatings from traditional synthetic resin emulsion coatings, and prevents unscrupulous enterprises from taking advantage of loopholes. It also adds sampling and preparation methods for the fire-resistance performance of inorganic coatings, providing a legal basis for testing the fire-resistance performance of inorganic coatings. By adopting a low-VOC testing method, the method's detection limit is increased from 2 g/L in GB 18582-2020 to 0.2 g/L, highlighting the environmental protection characteristics of inorganic coatings.
