Scrub resistance.
The performance of the products of Xuanwei and Caizhou brands in this random inspection is far below the requirements of national standards.
Scrubbing resistance is an important quality indicator of latex paint, reflecting the density and chalking resistance of the paint film surface.
Poor wash-resistance quality will cause wall delamination and powder drop.
In order to reduce costs, some companies have reduced the amount of emulsion and titanium dioxide added, choosing cheap and inferior emulsions or reducing the amount of emulsion added, resulting in unqualified scrubbing resistance.
