Sulfate Grde R618 for coatings
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,better leveling groperty.Large-scale production equipment, advanced DCS control system, as well as our company's strong technical fore and rich managem
