Abstract Epoxy nanocomposite coatings are an essential way to protect petroleum storage tanks from corrosion. For this purpose. the new nanocomposite epoxy coatings (P-M/epoxy composites) have been successfully designed. The P-M/epoxy composites are based on the metal vanadium oxy-phosphate M0. https://herbsdailyes.shop/product-category/vitamin-d/
