In order to make aluminum particles in the paint film could have excellent performance, the process of dispersion is very important. Usually the aluminum paste has been added necessary dispersant in the production process, so it has good dispersity in most time. But effect will bemore obvious after soaking in solvent before using.

The ratio of aluminum paste to solvent is usually the same ratio or more solvent. Soaking time is half an hour or more. The solvent-soaked aluminum paste should be completely dispersed in the coating system to ensure that there are no small particles such as aluminum particle polymers, especially after long-term storage or secondary use of aluminum paste. If the dispersing effect is not good after brief soaking, add wetting agent or dispersant to help the complete dispersion of aluminum paste. Aluminum flakes are easy to break or bend in high-speed mixing, so avoid to use high-shear dispersing equipment for soaking.
