The basic principles of the following waterborne wood paint formulation design
The amount of the emulsion or the aqueous dispersion is as much as possible because the material of the emulsion is mainly composed of a polymer material which is a backbone for ensuring the final film properties;
The additive are as few as possible, and they can be used without being used. These additive will be present in the film in a free state after film formation, which will inevitably affect the mechanical properties of the film;

The amount of pigments and fillers is preferably as small as possible, as long as the purpose is achieved, the less the better, the introduction of these materials necessarily means the introduction of grinding aids, thereby affecting the film properties.
