High-Quality Rutile Titanium Dioxide R-618 from China Suppliers and Factory - Superior Hiding Power and Weather Resistance
R-618 is rutile titanium dioxide made by sulfate process. It has an unparalleled hiding power due to the unique hydrolysis and calcination process. Advanced, fine grinding process make the particle size distribution more uniform and higher gloss. As a result of a special surface treatment, R-618 has a better weather resistance, lower oil absorption, and better leveling property.
Application
Can be widely used in coatings, ink, paper and other fields.
