Paint semi-product which has a higher pigment content and generally a higher viscosity then the finished paint.
In this paint production approach, a resin with a high compatibility range is selected as main dispersion resin and different pigments are dispersed separately to a certain grain size using this resin. Color matching is performed using this pigment pastes and letdown is done by adding remaining ingredients after a proper calculation. The main advantages of this approach are, better optimization of capacity of production equipment (especially the mills) and storage areas in addition to reduced production times. It is achieved by producing common pigment pastes, which can be used in various product groups owing to the compatible resin used. The drawback of this approach is the difficulties in sensitive color matching because of highly concentrated pigment pastes in addition to the possibility of decrease in color strength, gloss as well as haze and formation of particles due to pigment flocculation during storage.
