Performance Advantages of Ttanium Doxide R-5566
Superior Optical Properties: R-5566 titanium dioxide provides high tinting strength, hiding power (scattering power), brightness, and gloss for excellent finish appearance.
Excellent Durability: The inorganic coating enhances weather resistance and chalking resistance, suitable for exterior applications.
Outstanding Dispersibility: Exhibits easy and rapid wetting and dispersion in both water-based and solvent-based systems, improving production efficiency.
Good System Compatibility: A versatile pigment designed for a wide range of coating and ink systems.
Main Applications
(1) Paints & Coatings. The primary market. The titanium dioxide R5566 is ideal for architectural coatings (interior/exterior latex paints), industrial paints, powder coatings, coil coatings, and container paints.
(2) Inks. Suitable for both water-based and solvent-based printing inks requiring high opacity and gloss.
(3) Other Industries. Also used in paper and other applications needing white pigmentation.
Two Distinct Products: It is crucial to recognize that Pangang titanium dioxide R-5566 and Dongfang R-5566 are produced by different companies. They are not identical, despite the shared “R-5566” code.
Information Discrepancy: Publicly available specifications may differ or be incomplete. The definitive source is the official Technical Data Sheet (TDS).
Handling & Storage: Store in a cool, dry place on pallets. Keep bags sealed to prevent moisture absorption. Follow standard safety procedures for handling fine powders (use PPE, avoid dust generation).
Regulatory Status: Confirm suitability for intended use. For applications with specific regulatory requirements (e.g., food contact, toys), direct consultation with the manufacturer is mandatory to obtain compliance statements.
