In the article effectiveness of the use of fillers to improve the physical and mechanical
properties of the coating varied depending on the average size of the filler particles and
crystalline shape was studied. According to the indicators of impact strength to back impact and
bending strength of the coating, the most effective is the use of microsilica with an average size
of 2.9 μm. As the average filler size increases, the gloss and impact strength of the coating
reduce. To increase the bending strength of the coating, it is advisable to use fillers in the form
of wollastonite, which is characterized by a fibrous crystal shape, which improves the physical
and mechanical properties of the coating and prevents cracking, acting as a reinforcing agent. In
addition, the analysis of the obtained study results shows that the use of the studied Ukrainianmade
fillers in the powder paint composition promotes obtaining a covering with adjustable
physical and mechanical characteristics.
