The structure of epoxy-polyester-based coatings is characterized by high chemical resistance, good adhesion, thermal stability, and good mechanical properties. This Master Thesis is based on the addition of different percentages of hydrotalcite (1% and 3%) into the epoxy-polyester powder coatings, seeking an improvement in the properties of the coating, particularly regarding mechanical properties. The primary objective is to determine whether the differences between a commercial coating and those obtained with the addition of hydrotalcite can be characterized by Raman spectroscopy. In particular, whether Raman spectroscopy reveals differences in terms of wear between the coatings obtained with or without hydrotalcite. In order to obtain these results, a homogeneous distribution of the reinforcement in the polymer coating was achieved by means of a phase resonator, applied to steel sheets using an electrostatic gun, and finally, crosslinking was carried out in a laboratory oven.
