This article presents the results from an examination of the physical and mechanical properties of powder
coatings based on different binding agents, including epoxy, epoxy-polyester, polyester, polyurethane,
and silicone. The coatings that showed the highest results in all tests are epoxy, epoxy-polyester, and polyester. The study investigated the thickness and uniformity of coatings achieved under different spraying conditions. Specific spraying system modes were identified to achieve uniform coatings with predetermined thicknesses. The research highlights the potential application of powder coatings as
protective and matching layers for ultrasonic sensors.
