Aeroxide® TiO2 P 25 is a hydrophilic fumed titanium dioxide. Acts as a catalyst. Used in sealants.
Details
13463-67-7
Hydrophilic fumed titanium dioxide
- High specific surface area and high purity
- Crystalline TiO2 with predominantly anatase structure
- Very good thermal and chemical stability
- Outstanding catalytic and photocatalytic efficiency
- Photoactive under UV-B radiation
- Heat-stabilizing effect in silicone elastomers through the influence of titanium dioxide on redox processes
Raw material for catalyst substrates with high thermal and hydrothermal stability
Efficient photocatalyst for formulation of self-cleaning construction materials, such as concrete or mineral plasters
Suitable for the construction of efficient dye-sensitized solar cells
Efficient and overdyable heat stabilizer for silicone vulcanizates at process temperatures to more than 200 °C
Improvement of the flammability protection of silicone vulcanizates
Additive and raw material for ceramic and metal materials as bonding agent, sintering additive, or structural component
sealants
We recommend to store the product in closed containers under dry conditions and to protect the material from volatile substances. Aeroxide® TiO2 P 25 should be used within 2 years after production.
