Sažetak
The purpose of this study was to investigate and develop a polyaspartic coating, using nano- silica modified with an amino group (NH2-) in order to enhance adhesion on metallic surfaces and increase the effectiveness of the coating protective action against corrosion. Seven samples of polyaspartic coating with different amounts of nano-silica were prepared and applied to low carbon steel plates. The results showed that only 2% of the nano-silica per total weight formulation gave excellent protective as well as physical properties to the coating. The unique result was non- agglomeration and compatibility of nano- particles with the other compounds in the formulation structure. Time dependant behaviour of the coatings was followed by the EIS, SEM and FTIR methods and by exposure in a salt spray chamber. The main advantage was superior mechanical and chemical resistance and durability of a single coat, the properties that reduce emission of VOC and overall cost of the coating application process.
