how to design a formulation of water base plastic paint

一克半

For basecoat, the formulation could be designed as two parts as the following
Part one: Binder
          1. Resin
          2. Defoamer
          3. Substrate Weting agent or/and surfactant
          4. Co-solvent
          5. DI-water
          6. Thickener
          7. pH adjust agent
Part2: color
         1. Pigment
         2. Dispersant
         3. Millling Resin
         4. DI-Water
You could preproduce some colors(Color tint, Al, Mica, etc.) in part2 for the color match.

Note: a. Resin selection is an very important step for the formulation, which decide the dry film properties.   
          b.  Additives keep the formulation stable and the good application properties
