Characteristic of ALUMINASOL
TEM image
- AS-200（Feather-like particle）
- AS-520-A（Granular particle）
Thixotropic property of AS-200
- AS-200 has thixotropic property and its viscosity increases remarkably as time goes by.
AS-520-A does not have thixotropic property.
Electric charge
- Isoelectric point of ALUMINASOL is around pH 9-10. It can be dispersed stably in acidic pH range.
