Make acrylic paint easily from dispersion and pigment yourself!
The binders for acrylic paints are synthetic resins in the broader sense. These can be different types of acrylic resins, but also polyvinyl acetates or polyurethane resins. Most of these synthetic resins are soluble in solvents. They are usually insoluble in water, so the solution is to make dispersions (a heterogeneous mixture of two or more substances that do not dissolve in each other).
Acrylic paints first dry by evaporation of the water contained in the dispersion. In the process, the film shrinks due to the loss of water and the dispersion becomes insoluble in water. The duration of drying depends essentially on the dispersion, the film thickness and the room climate.
