Kmeris® MT-7008HB is a functional micro titanium dioxide (Nano/Micro TiO₂) specifically designed for metallic paints and high-decorative coatings. MT-7008HB not only provides excellent UV shielding performance but also delivers a unique blue-phase hue and strong optical color travel effect through precise particle size control. It delivers a pronounced flip-flop effect (color travel effect) and is widely used in:

Automotive OEM and Refinish Paints
Industrial Metallic Coatings
Facade Coatings
Wood Paints
Aircraft Skin Coatings

Performance Highlights

1. Excellent Dispersibility & Transparency
Unlike conventional pigment-grade TiO₂ (200-350 nm) that relies on opacity, MT-7008HB features a controlled particle size of ~80 nm (D50). The ultra-low agglomeration index (3.2) means easy deagglomeration in coating systems, reducing milling time and energy consumption while maintaining high transparency in the film, allowing the sparkle effect of metallic base pigments to shine through.

2. Strong Flip-Flop Effect & Blue Phase
The product features a special inorganic aluminum/zirconium surface coating. This not only improves light stability and weather resistance (prevents chalking and yellowing) but also optically induces a strong blue phase. In automotive paint applications, the face exhibits high brilliance while the flop reveals a deep blue hue, significantly enhancing the premium appearance of the coating.

3. Superior Weather Resistance & Anti-Aging
As a rutile material, MT-7008HB possesses high UV absorption capacity (UV Absorbance 1.2-4.0), effectively protecting underlying resin and substrates from UV degradation, thereby extending coating service life. The inorganic coating further isolates the substrate from direct contact, preventing chalking or blooming.

MT-7008HB is a high-performance alternative to mainstream micro titanium dioxides on the market，such as:

MT-700HD
RM200
MT500HD
UV-TITAN L 530
