Read MoreSend InquiryThe Zinc oxide powder 997 produced by MST is a white pigment, also known as zinc white. Zinc oxide powder 997 does not turn black when it encounters H2S gas, because ZnS is also white. When heated, Zinc oxide powder 997 gradually changes from white to light yellow to lemon yellow. When it cools, the yellow fades away. Using this feature, it can be mixed into paint or added to a thermometer to make a color-changing paint or a color-changing thermometer. Because Zinc oxide powder 997 has astringency and a certain sterilization ability, it is often used in medicine as an ointment; Zinc oxide powder 997 can also be used as a catalyst, feed, rubber, tires, electronics, medicine, food, antibacterial cloth treatment and other industries.
