Specialized industries have different requirements for fumed oxides with specific properties. In order to fulfill these high technical requirements, combinations of different raw materials (SiO2 or TiO2), treatments and many manufacturing processes are employed.
The R and N grades of AEROSIL® products listed above can be used to regulate the electrical charge of polymers. AEROSIL® DT 4 was specially developed for highly-loaded dental composites. AEROXIDE® LE 1, LE 2 and LE 3 provide a Lotus-Effect® to plastic surfaces. AEROXIDE® TiO2 T 805 is characterized by its ease of dispersibility and low moisture adsorption. AEROXIDE® Alu C 805 is especially recommended for moisture sensitive powder coating applications.
Positive Effects:
- Regulation of electrostatic charge in toner
- Free-flow agent for toner
- Improved storage stability of toner
- High-loading levels in dental composites
- Increased light protection factor, e.g. sunscreen products
- Lotus-Effect® for the self-cleaning of surfaces
- Increased heat stability of silicone elastomers
