FIELD: chemistry.
SUBSTANCE: costing is obtained from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average size of the particles ranges from 0.1 to 50 mcm. The particles have hardness which is sufficient to endow the coating with high resistance to dents and/or scratches compared to a coating in which such particles are not present. Also, the difference between the refraction index of the resin and the refraction coefficient of the particles ranges from 1 to 1.5. The invention also describes a method of preparing a powdered coating which includes particles dispersed in the resin and a coated substrate.
EFFECT: after hardening, the coatings have high resistance to dents and scratches, high resistance to breaking caused by mechanical impacts, as a result of mechanical or chemical wear.
