In the solid paint, white paint is taken as an example. The amount of titanium dioxide should be sufficient to ensure that the paint film has sufficient capping power. The amount of titanium dioxide should not be lower than 13%, but it is not necessary to be higher than 22%. The situation is the same as solvent-based white paint.
Fillers may be added or not added. However, a small amount of filler must be added to the water-based putty, such as talc, heavy calcium, and zinc stearate. The total amount can be between 15% and 30~//oo. The more filler, the worse the transparency of the putty, but the better the interstitial.

Colorants include pigments and dyes. Pigments are used in solid paints (coating without revealing wood grain) and dyes are used in clear paints (painting of wood grain). When there is a pigment filler in the formulation, a wetting and dispersing agent of 2% to 10% of the total amount of the pigment filler is added to help disperse the pigment filler.
