14. What substances are included in a paint?

The basic ingredients of paint are:
Resin - a film forming substance whose main function is: forming a protective-decorative coat, adhering to the surface being painted, giving appropriate strength parameters (e.g. resistance to washing and weather).
Pigments- insoluble solid coloured or white substances used to give a paint coat: correct covering power, appropriate colour, protective functions (e.g. anticorrosive pigments).
Fillers - insoluble solid substances, usually white, differentiated by: size of grain, weather resistance, structure (plate and spherical fillers), chemical structure (carbonates, dolomites, talc). They are the main ingredient of paint. A correct combination of fillers in a paint helps to modify viscosity, covering, resistance to external factors, and gloss.
Diluents - liquid paint phase in which pigments, fillers and paint vehicle are suspended. Thickeners system – the types of thickeners: cellulose, acrylic, polyurethane. They are used mainly to form a homogeneous mixture of all ingredients of paint and to give it appropriate application characteristics.
