Composition of paintwork materials
Each of us at least once in my life had to paint something. At the same time, the question arose: which paint is better to buy, so that it retains its original appearance for a long time. In order to choose the right paint for certain surfaces, it is necessary to understand the types and composition of paints and varnishes.
Any paint is a composition of several components. Binder (film former) is a polymer that forms a protective film with good adhesion to the painted surface. In addition, the film former holds the remaining paint components.
A coloring agent is a pigment in the form of a highly dispersed powder of a certain color, which has optical activity, i.e. intensely reflects light waves.
Fillers are also highly dispersed powders, which have a low refractive index and lack their own color tone. They are designed to improve weathering and adhesion of coatings.Raw materials for fillers different cheapness.
In the role of the liquid part is the solvent or water.
In addition, the paint may contain many other additives with various useful functions, however, the above components are the main ingredients.
