7H-Naphth[1,8-gh]isoquinoline

7H-Naphth[1,8-gh]isoquinoline is a compound produced from various materials including antioxidants, corrosion inhibitors, resins, solvents, and additives. After drying, it comes in two colors: transparent and golden yellow. It can be applied by immersion, brushing, or spraying to the metal surface requiring rust protection. After drying, it forms a non-sticky dry film on the metal surface, maintaining the original appearance of the parts and increasing their shine. It can provide medium- to long-term protection against corrosion and rust.
