Anti-Rust Coating – Types Commonly Used

When the processes that operate your machinery and equipment are running at full speed, it is important to have confidence that these processes will continue without interruption. Any delay in your production can mean lost profits. If a machine component malfunctions in the field, the culprit is often rust or corrosion of some type. In order to avoid these issues, it is important that machinery and equipment are properly treated with anti-rust coating.

The scenarios involving this type of corrosion can be prevented by applying the proper coatings to machine parts and tools. These coatings can help prevent the deteriorating effects of corrosion. Also referred to as anti-rust coating, this type of coating is effective with many types of applications and can help ensure that manufacturing processes are able to function smoothly and without unnecessary downtime.

The types of coatings that are used in various environments and for different alloys include:


Components that are subjected to corrosion as a result of rust can benefit significantly from the application of epoxy coatings. These coatings often have a 4 to 6 mm thickness, and may also be applied at a thickness of 8 mm in other applications that are threatened by rust. These coatings have a high resistance to chemical erosion.

Inorganic Zinc

In general steel surfaces can benefit significantly from the use of inorganic zinc coatings. They provide protection against saltwater and adverse weather conditions, and are excellent at defending against rust. These coatings are often used in refineries and chemical plants to protect machinery and equipment components

Phosphate Coating

Used often for rust prevention, anti-galling, and lubricity, the crystalline conversion coating phosphate is manufactured via a pickling process. If the purpose of the coating is to provide corrosion protection, the surface must first receive a sealer coating due to phosphate coatings porous characteristics. Surfaces such as silver, tin, aluminum, zinc, and cadmium can benefit from phosphate coating.

With the proper anti rust coating applied to parts, tools, and components, you can ensure that your operations are kept free from unnecessary delays and also save money on premature replacements or repairs of your machinery, equipment, and parts.
