1.Alkali resistance: It is very stable to any concentration of alkalis and other types of alkaline substances, and it will not affect the strength of cement.

2.Acid resistance: it is resistant to weak acids and dilute acids, but it can also gradually dissolve in strong acids

3.Light fastness: Its color remains unchanged under intense sunlight exposure.

4.Heat resistance: within a certain temperature range, it will not change, but the color will start to change beyond its temperature limit,  the degree of change will become more significant with the temperature increasing,

5. Resistant to climate influence: the hot and cold weather and the humidity of the air have no effect on it.
