TINOX R-2290 Rutile Titanium Dioxide
TINOX R-2290 Rutile Titanium Dioxide
Overview: TINOX R-2290 is a premium rutile titanium dioxide pigment specifically engineered for plastic applications requiring exceptional weatherability and long-term performance. Its unique combination of properties, particularly the silicon-based post-treatment, makes it ideal for demanding outdoor applications.
Key Features
R-2290 exhibits a vibrant blue undertone that enhances the visual appeal of plastic products while maintaining excellent color consistency. This blue base provides superior color balance in various plastic applications.
The pigment delivers outstanding opacity with minimal pigment loading, ensuring cost-effective coloration while maintaining excellent visual performance. This is particularly valuable in applications requiring solid color coverage.
The silicon-based post-treatment provides exceptional resistance to weathering, UV exposure, and environmental degradation. This makes R-2290 ideal for long-term outdoor applications where color retention is critical.
