In the field of metal processing and equipment maintenance, corrosion and rust have always been unavoidable challenges. Whether it is precision molds, automotive parts, or large mechanical structures, once the surface rust occurs, it not only affects the appearance, but also may reduce strength, shorten life, and even cause safety accidents. It is particularly important to choose an efficient, stable and adaptable anti-rust oil. Hank Metal Anti-rust Oil BS-400 series is such a professional product specially designed for the needs of the whole scene. With its excellent anti-rust performance, flexible applicability and simple operation, it has become a "rust-proof weapon" trusted by many enterprises.

First, the core advantage: more than rust prevention

Hank BS-400 series anti-rust oils are refined with composite anti-rust additives and high-performance base oils, which can quickly form a dense and uniform protective film on the metal surface. This film can effectively isolate moisture, oxygen and corrosive media in the air, and block the occurrence of electrochemical corrosion at the root. Compared with traditional anti-rust oils, the BS-400 series has the following outstanding features:

1. Long-term anti-rust and strong weather resistance. The BS-400 series has undergone strict salt spray test and damp heat test, which can provide a protection period of months or even years in indoor environments, and can also significantly prolong the anti-rust time in outdoor or humid environments. The protective film formed by it is not easy to be initialized by rain or evaporation failure, especially suitable for long-term storage or transportation of metal products.

2. Good permeability, covering complex surfaces. For workpieces with small gaps, grooves or threaded structures, the BS-400 series has excellent penetration ability, which can penetrate deep into surface micropores to ensure that every corner is protected. This feature is especially important for precision parts and assemblies, avoiding local rust caused by coating dead ends.

3. The oil film is thin and transparent, which does not affect the follow-up process. Anti-rust oil often faces the contradiction between "rust prevention and cleaning", but the oil film formed on the surface of the workpiece by the BS-400 series is moderate in thickness, transparent and non-sticky. When subsequent assembly or welding is required, no complicated cleaning treatment is required. Some models can even be assembled directly with oil, effectively simplifying the process and reducing labor costs.

4. A variety of models, suitable for different scenarios. The BS-400 series is subdivided into a variety of specifications, including solvent type, oil type, water-based dilution type, etc., which are suitable for short-term rust prevention, long-term storage, dry environment or high-humidity salt spray environment. Users can choose the most suitable model according to the actual working conditions to achieve precise protection of "one product, one policy".

In addition, the BS-400 series also takes into account the needs of environmental protection and safety. Some models are formulated with low VOC to reduce the burden on operators and the environment. Whether it is high-volume processing in factories or fine spraying in small workshops, it can provide stable and reliable performance.

Second, a wide range of applications covering the entire scene

The reason why the BS-400 series is called the "all-scene rust prevention weapon" is that it covers almost all industries and links that require metal protection. From the parts that have just rolled off the production line, to the machinery and equipment in the sea, to the spare parts in the warehouse, the BS-400 series can provide reliable protection.

1. Machinery manufacturing and metal processing. During turning, milling, planing, grinding and other processing processes, the surface of the workpiece is prone to rust due to cutting fluid, hand sweat or environmental humidity. The BS-400 series can temporarily prevent rust during the process to prevent red rust during work in progress. At the same time, it is also suitable for the sealing and packaging of the final product to ensure that the product is still as bright as new when delivered to the customer.

2. Automotive and parts industry. Automotive engines, transmissions, chassis parts, etc. are under high temperature, vibration and complex chemical environment for a long time, and have extremely high requirements for rust prevention. The BS-400 series can adapt to a variety of materials such as cast iron, carbon steel, alloy steel, galvanized parts, and has a good protective effect on precision fittings such as fasteners and bearings. Many auto parts suppliers use it as the last processing process before leaving the factory.

3. Hardware tools and cutting tools. Hand tools, power tools, knives, measuring tools and other metal products will soon lose sharpness and accuracy if they are not properly rusted. BS-400 series oil film is thin, has a long anti-rust period, and does not affect the feel and appearance of tools, so it is widely used in packaging anti-rust in tool manufacturers and daily maintenance in homes and workshops.

4. Ship and Marine Engineering. The high salt and humidity in the marine environment are the "accelerators" for metal corrosion. The heavy protection models in the BS-400 series are specially designed for scenarios such as ship equipment, port machinery, offshore platforms, etc., which can effectively resist salt spray erosion and provide protection for critical components for months of sea transportation or berthing.

5. Electronics and precision instruments. For electronic manufacturing fields that require electrostatic protection or to avoid oil pollution, the BS-400 series also introduces low-residue, fast-drying products. It can form an extremely thin protective layer on metal shields, heat sinks, connectors and other components, which can prevent rust without affecting electrical conductivity or assembly performance.

6. Power and new energy equipment. Transformer casings, wind tower bolts, photovoltaic brackets, charging pile casings and other new energy equipment are exposed outdoors for a long time, and the environment changes drastically. The BS-400 series can provide excellent anti-ultraviolet aging and anti-heat performance, reduce the maintenance frequency of outdoor equipment, and ensure the long-term stable operation of power stations and charging networks.

7. Agricultural machinery and construction machinery. Harvesters, tractors, excavators and other equipment often operate in muddy and rainy environments, and are prone to rust after downtime. Regular spraying of key parts with the BS-400 series can effectively inhibit rust, prolong the service life of equipment, and reduce maintenance costs.

8. Daily industrial maintenance and home applications. Whether it is the guide rails, chains in the factory, or scissors, kitchen knives, and door hinges at home, regular use of the BS-400 series for painting or spraying can effectively extend the service life of metal products. Its spray can is easy to use and can be evenly covered by easy pressing, making it ideal for daily maintenance.

Third, the scientific use of methods allows rust prevention to achieve twice the result with half the effort

To get the most out of the BS-400 series, proper use is essential. Here are some proven operating recommendations:

1. Surface cleaning. Before anti-rust construction, oil, dust, water stains and old rust layer on the metal surface should be removed as much as possible. It can be treated with cleaning agent, degreaser or grinding. A clean surface can ensure that the anti-rust oil is well wetted and tightly adhered.

2. Coating method. According to the size and quantity of the workpiece, you can choose to soak, brush, spray or automatic line coating. For sporadic parts, aerosol cans or spray guns are recommended; for small batches, the dipping method is more efficient; for large surfaces, brush and roll coating are more practical.

3. Control the thickness of the oil film. The thicker the oil film, the better. Too thick not only wastes material, but also may cause sagging or affect assembly. The BS-400 series is generally suitable for uniform, continuous and leak-free coating. For long-term sealing parts, the thickness can be appropriately increased; for short-term rust prevention, a thin layer is sufficient.

4. Ventilation and curing. When using solvent-based products, the site should be well ventilated to form a dry protective film after the solvent evaporates. Oily products do not require special curing, but should avoid contact with moisture or dust immediately after coating.

5. Regular inspection. The anti-rust oil film may be damaged due to mechanical wiping or environmental factors during long-term storage. It is recommended to check the anti-rust status regularly. If local damage is found, it should be reapplied in time.

6. Pay attention to the environment and storage. Unopened anti-rust oil should be stored in a cool, dry and ventilated place away from direct sunlight. Cover the container tightly after opening to prevent impurities and moisture from mixing in. Too low ambient temperature during use may cause viscosity to increase. It is recommended to operate at an appropriate temperature.
