Rutile Grade Titanium Dioxide R-6618

R6618 is a titanium dioxide pigment with zinc salt stabilizer, zirconium, aluminum, silicon envelope. With high blue phase, easy dispersion, high weather resistance, high covering force, low oil, good system compatibility, very good processing rheology, is a high quality plastic special titanium white powder.

R6618 is a zirconiumn, aluminum and organic surface treated multipurpose rutile titanium dioxide piginent, it hasaverage particle size distribution, good whiteness, good dispersion, high gloss, good hiding power and high weatherresistance properties. It is widely used in coating, paints, ink, leather, rubber and ink production.

R6618 is a white powder pigment coated with inorganic zirconium aluminum and organic surface treatment. It has excellent optical properties, excellent whiteness and gloss, low oil absorption, good hiding power and weather resistance, and easy dispersion.

  • High covering force:When the hiding force refers to the ability of the pigment in the coating, the pigment in the coating can cover the base color of the coating material, so that the substrate of the subject cannot be revealed by the coating.
  • High gloss:Gloss refers to the reflection capability of the material on refraction, the stronger the ability to reflect, the greater the gloss.

4. Package and storage:
Titanium dioxide R6618 are package by 25 kgs.
It could be stored well for a long time by avoiding directly to contract with moist environment.
