Product Description
HTR-636 undergoes inorganic surface treatment with silica and alumina, and is modified on the surface using organic agents such as TMP. It features excellent whiteness, easy dispersion, and strong hydrophilic properties, making it particularly suitable for water-based coatings while also applicable in general-purpose fields. As a multifunctional and specialized rutile titanium dioxide, it can be widely used in water-based coatings, PVC profiles, exterior wall paints, topcoats, road marking paints, rubber, and other fields.
Main Features
- Excellent water dispersibility
- Excellent weatherability, heat resistance, and lightfastness
- Excellent tinting strength and hiding power
- Excellent whiteness with wide applicability across various fields.
Applicable scope
- water-based coatings
- Plastic steel profiles (in the fields of plastics, inks, rubber, leather, etc.).
- Outdoor decorative paint
- Road marking paint
- Marine paint
