Product Communication:
Specification: R2 (ISO 591) II、III、IV (ASTM D476)
Surface treated: Aluminium oxide,Silicon oxide,Organic compounds
Specific gravity (g/cm3): 4.1
Product Characteristics:
Rutile type ZR-940+ has high level of whiteness, lightening power, gloss, hiding power,easy dispersion,excellent weather resistance and chalk resistance.
ZR-940+ is improved on universal type ZR-940.It has smaller particles,organic treatment and surface treatment with silicon and aluminum,so ZR-940+ has excellent hiding power,high weather resistance and dispersion,especially suitable for coating.
Application:
Suitable for high-grade indoor and outdoor coatings，both water-thinnable and solvent-borne(industrial, architectural, decorative),printing ink. This pigment can also be successfully utilized for plastic, rubber, paper and leather, etc.
