The main difference between wax for latex paint and solvent-based paint
The difference between resins
Solvent-based resin is a real polymer solution, that is, it can spontaneously form a single-phase homogeneous molecular dispersion system in the solvent, and it is a thermodynamically stable system. The polymer solution is not a lyophilic colloid but a true solution. It is a molecular dispersion system rather than a colloidal particle dispersion system.

Emulsion is a hydrophobic colloid, it is the hydrophobic colloidal particles dispersed in the continuous phase (water) through the third component (emulsifier), thermodynamically unstable system.
The similarities of these two types of resins are: the molecular or colloidal particle diameter is similar, about 10-7~10-%cm, the diffusion speed is slow, and neither can penetrate the semi-permeable membrane.
The main difference is that the molecules of the solvent-based resin have affinity with the solvent (automatically dissolve into a solution), and the viscosity is high. The dispersed phase in the emulsion has no affinity with the continuous phase (water) and requires a third component emulsifier, so the viscosity is lower when the solid content is less than 40%.

The difference between the above resins determines the essential difference between latex paint and solvent-based paint in formulation design and testing methods.

The difference between the principle of dispersion
According to different resins, solvent-based paints can be used alone or together with dispersants to grind and disperse pigments and fillers. The emulsion used in latex paint generally cannot participate in grinding, and high-speed shear will cause emulsion breakage.

In latex paint, the inorganic pigments and fillers must be prepared into a slurry before the paint can be adjusted. At this time, the dispersion principle and the additives used are different from the solvent-based paint.

The difference between pigment and filler suspension principle
Latex paint is actually a kind of mixed colloid. The low viscosity and low density of continuous phase water cannot keep high-density inorganic substances suspended and stable in the paint for a long time. It is easy to cause phase separation, so thickeners are necessary.
