Introduction
Product Description
This oil is a brown-yellow translucent oil, made of environmentally friendly solvent film-forming agent and a variety of special anti-rust additives. When it acts on the surface of the product, the solvent evaporates to form a uniform thickness of anti-rust hard film, which is not easy to fall off. It is suitable for rust prevention of cast iron and various steel alloys. At the same time, we have added STD vapor corrosion inhibitor. When STD molecules evaporate into a confined space, they will form a protective barrier on the metal surface, so that the metal can be better protected.
Main advantages
1. This product has extremely low viscosity and does not leave sludge. After use, the solvent evaporates quickly to prevent dripping during use, making the process clean and tidy;
2. The anti-rust cycle is long, leaving an ultra-thin dry film with extremely strong anti-rust performance on the metal surface. The film can effectively resist chemical erosion by air, water and other liquid and solid particulate matter. Good permeability enables it to penetrate into the narrow gaps that are difficult for general rust preventives to reach, making it truly foolproof;
3. Low cost, because the oil film is extremely thin and volatile, the amount used is small, and 50-60 square meters can be applied per liter, with low unit cost;
4. The indoor anti-rust period is at least 2 years, and the outdoor period is at least 1 year.
5. Easy to clean, forming a transparent oily film on the metal surface, which can be easily washed off with petroleum solvents or kerosene.
6. Easy to operate, spray, paint, brush, and immerse.

Packaging and storage
20L/200L barrels are sealed and stored in a cool, dry, clean, and ventilated warehouse at room temperature.
Use and method
1. Widely used in the anti-rust treatment of various types of steel, hardware parts, mechanical products and other metals, which can be used by dipping, spraying, coating, etc. The metal surface must be oiled, and complex-shaped workpieces should be immersed as much as possible.
2. Before oiling, the metal surface must be cleaned and there must be no stains or moisture on the surface, otherwise the anti-rust effect will be affected.
3. Pay attention to proper labor protection during use.
