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
Strong Blue Undertone: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.
Exceptional Opacity and Hiding Power: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.
Superior Weatherability (Internal Classification A):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.
Technical Advantages
- Silicon-Based Post-Treatment (Si):
- Enhances weatherability and UV resistance
- Improves surface protection and durability
- Provides superior long-term color retention
- Inorganic Post-Treatment: Enhances heat resistance and overall stability
- Hydrophobic Organic Treatment: Provides excellent moisture resistance and processing stability
- Superior Dispersibility: Ensures easy incorporation into plastic matrices
- Low Volatility: Maintains consistent performance at high processing temperatures
- High Temperature Resistance: Suitable for demanding processing conditions
Common Applications
High Concentration Masterbatch (especially for outdoor
applications)
Consumer Electronic Plastics (where long-term appearance is
important)
Polypropylene (PP) products for outdoor use
Polystyrene (PS) applications requiring weather resistance
ABS plastics for outdoor consumer goods
PVC products with weatherability requirements
Window Profiles: Particularly for PVC window frames and other building components
exposed to weather, where the silicon-based treatment provides
superior long-term protection against UV degradation and color
fading
Other outdoor plastic applications requiring exceptional weather
resistance
