5040 Water-based Long-lasting Corrosion Inhibitor for Steel

Environmentally Friendly: 5040 is made from sustainable materials, contains no harmful substances, ensuring a green choice for industries focused on environmental protection. It can reduce environmental impact during production and use.

Harmless: Due to meeting strict safety standards, and also being free from substances like sodium nitrite, 5040 poses no risk to human health or the environment. This makes it safe for workers handling the product and for the end-users of the treated metal items.

Wide Applicability: Being applicable to a variety of iron-containing materials such as cast iron, carbon steel, and more, 5040 as a rust inhibitor for industrial metals and metal products, can be used in different industries, from automotive to machinery manufacturing, providing a versatile rust prevention solution for various metal components.

Process Compatibility: It can replace the phosphating process without interfering with subsequent operations like welding, spraying, and silk-screening. This would save time and cost in the manufacturing process and can ensure seamless integration with existing production lines.

Long-lasting Rust Prevention: With a rust prevention time of 8 - 16 months or more, 5040 offers reliable and long-term protection for metal products. This can help to extend the lifespan of metal components, reducing the need for frequent replacements and maintenance.

Industrial Production: 5040 as a professional rust prevention for metal workpieces and metal processing parts, can be widely used in the manufacturing and maintenance of steel parts, metal processing parts, castings, forgings, cylinder liners, crankshafts, bearings, water pump machinery, etc., for rust prevention during processes, for semi-finished and finished products.

Electroplating and Phosphating: 5040 can be used for passivation and rust prevention treatment of electroplated and phosphated parts, enhancing the corrosion resistance of electroplated layers and phosphating films.

Preparation: Before using, shake the barrel several times and pour out the original liquid. For the rust prevention working liquid, it can be used directly as the original liquid for soaking. The soaking time is 2 - 10 minutes (usually 2 - 3 minutes is sufficient). The temperature can be from normal temperature to 50°C (usually normal temperature is fine, but for faster drying of the rust-proofed workpiece, it can be heated to 40 - 50°C).

Surface Preparation: Before rust prevention treatment, ensure the workpiece surface is free from oil contaminants, rust, and granular attachments. The higher the surface finish, the better the rust prevention effect. If acidic water is used for rust removal, rinse the workpiece with flowing water at least twice to make the surface neutral.

Treatment Method: For large and complex workpieces, if using spraying or brushing, ensure the liquid fully wets all corners of the workpiece. After treatment with the rust prevention liquid, it is recommended to use a spray gun with compressed air to blow off the residual water on the surface and in all corners, then dry it. If possible, it is better to dry it in an oven. The dried workpiece should be placed on a dry packing box or a ground with a wooden board as the base.

Maintenance: The rust prevention working liquid usually does not reduce in concentration but decreases in quantity. Add the original liquid and clean water according to the proportion. If the rust prevention agent is contaminated by tap water or cleaner residues and cannot effectively prevent rust, a new tank needs to be opened. It is recommended to open a new tank at about the same time as the cleaner tank.
