Dar-Tech Ti-Pure - R-105 - 13463-67-7

Ti-Pure™ R-105 technology has optimized SiO₂ encapsulation for durability. By providing a uniform, complete coating of the TiO₂ surface, the SiO₂ layer acts as a barrier to prevent the surface of the TiO₂ from reacting with the polymer or additives. This is especially important in outdoor applications where the UV energy absorbed by the TiO₂ particle may induce photocatalytic reactions. Ti-Pure™ R-105 provides excellent gloss retention in outdoor PVC applications.

Discoloration Resistance

The combination of surface treatments used in Ti-Pure™ R-105 provides excellent resistance to photo-induced discoloration. Ti-Pure™ R-105 minimized lead graying in PVC systems and phenolic yellowing in polyethylene systems.

Suggestions for Use: Ti-Pure™ R-105 is recommended for outdoor plastics, especially PVC window profile applications. Ti-Pure™ R-105 utilizes silica encapsulation technology to minimize interaction of the TiO2 surface with the surrounding environment. This minimizes “chalking,” crazing, and other surface deterioration frequently seen in outdoor applications. Ti-Pure™ R-105 surface treatment also is optimized for dry flow conveyability and dispersion within plastics.
