first of all, you have to find which purpose the plastic component to be used,for mobile,CE or auto? then, which kind of plastic want to be coated ,ABS,PE,PP,Nylon or others?
third,which kind of resin and curing method is suitable.
know,we can design the formula

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

thank you for your advice.
your commend formulation listed the basic component.
how to design the formulation which include the following steps:
1.select the basic component
2.what kind of substrate
3.the primer,basecoat or top coat
4.how to determine the pvc?
5.select the binder。
6.select the additive
