This guide provides standardized procedures for testing waterborne architectural coatings for Coatings on external, internal or dual-use surfaces. The guide covers the evaluation of liquid Coatings properties, including density, flash point, dilute Stability, etc.; coating application performance, such as brushing, roller coating and lame plating uniformity, drying performance, etc.; Dry-Film Appearance and performance, including Color, Gloss, adhesion, abrasion resistance and chemical resistance, etc. Also includes chemical analysis and physical property testing of Coatings. Through these testing methods, the practical application effect and performance of the Coating can be fully evaluated to ensure that it meets the expected use standards.
