Product Description
HTR-628 is treated through inorganic surface modification using zirconium oxide and alumina, and further enhanced with the organic agent TMP. The product exhibits superior whiteness, excellent dispersibility, and balanced hydrophilic-oleophilic properties, making it suitable for a wide range of applications. As a versatile general-purpose rutile titanium dioxide, it is widely applicable in coatings, plastics, inks, topcoats, rubber, and other related fields.
Main Features
- Excellent whiteness
- Excellent tinting strength and hiding power
- Excellent dispersibility in both water-based and oil-based systems
- Exhibits high weatherability, heat resistance, and lightfastness, with broad applicability across various fields.
Applicable scope
- Decorative paint (for indoor and outdoor use)
- Powder coatings
- Coil coating (applicable in plastics, inks, rubber, leather, and other fields).
