Benefits of adding zinc oxide to coating
High purity painting grade zinc oxide is added to the coating, which has a good covering effect and can be used as an antiseptic
High purity painting grade zinc oxide can make the coating film of the product more flexible, more stronger and impervious to water, so high purity painting grade zinc oxide is can prevent metal corrosion. But it should not be mixed with the base material with more free acid. If mixed, it will produce more zinc soap, which makes the coating thick and not easy to apply.
In addition, high purity painting grade zinc oxide is used in anticorrosive coatings or marine coatings. It can form dense zinc-titanium compounds, which can reduce the rate of further penetration of corrosive media into the material. Mainly high purity painting grade zinc oxide plays the role of anti-rust. And it has anti-mold and can inhibit the growth of microbial fungi.
High purity painting grade zinc oxide is supplied byMTS Chemical can meet all the requirement of the painting.
