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 ste... https://seriouswatchers.shop/product-category/lady/
