Discription:
Titanium dioxide, molecular formula is TiO2.
It is knowed as the best white pigment in the world. Have rutile TiO2 and anatase TiO2, for the outdoor products require with high weather ability, just can use rutile TiO2, and the anatase TiO2 mainly use in he product require good whiteness but lower weather ability.
Usage:
This product have very good whiteness, stable chemical property, high purity, particle distribute evenly.good optical property, good tinting power. good covering power. good dispersibility.
