GB/T 21090-2007 "Tintable Emulsion Base Coat" specifies the technical requirements, test methods, and inspection rules for tintable emulsion base coats. It applies to architectural emulsion base coats used in conjunction with colorants. The standard covers indicators such as condition in the container, workability, scrub resistance, and compatibility. Compatibility is evaluated based on the stability after mixing with standard colorants. Testing requires instruments such as scrub resistance testers, viscometers, and adhesion testers to ensure the tinting effect and performance of the base coat when combined with colorants.
