Before use, pre-disperse the aluminum paste with the solvent. Generally, the ratio of aluminum paste to solvent is 1:2. During the dispersion process, use low-speed stirring. Avoid stirring too fast, which will cause high shear force to destroy the shape of the aluminum paste and reduce the brightness. The best dispersion speed should be determined through experiments. This depends on many factors and the geometric dimensions of the stirring equipment (ratio of the diameter of the stirring disk to the diameter of the container, the shape of the stirring disk, etc.), temperature and viscosity of the coating, solvent selection and the amount of aluminum paste added (see the table below)
