Performance index 1: resistance to scrubbing times. The number of scrub times mainly depends on the content and quality of the emulsion, and this main raw material also determines the main properties of the emulsion paint, such as the number of scrub resistance, weather resistance and color retention. The scrubbing resistance of good wall paint products is basically more than 5,000 times, and more attention should be paid to the comparison of scrubbing resistance times for ultra-white products on the market.
