See viscosity table
1. Highest viscosity shall be obtained by completely mixing or agitating both before and after the addition of the product.
2. Direct addition of the product with surface treatment into alkaline water solution will lead to the failure of the surface treatment, resulting in gel. Therefore, product with surface treatment can not be added into the alkaline water solution directly.
3. The concentration of the prepared solution shall be determined according to the product viscosity. The solution concentration of product with low viscosity (lower than 400mPa.s) is10~15%, and the solution concentration of product with high viscosity (more than 30000mPa.s) is 2-3% at most.
