Why Use CRC SP 400?
CRC SP 400 is a professional wax-based outdoor corrosion inhibitor designed to provide long-term protection for metal surfaces exposed to harsh environments. This 5-litre industrial pack creates a durable waxy protective coating that shields metal from moisture, humidity, salt water, and other corrosive elements. Manufactured for industrial and marine applications, CRC SP 400 delivers reliable outdoor corrosion protection for up to 2 years under normal storage conditions.
The advanced wax formulation forms a flexible protective film that does not become brittle over time. As a result, metal components remain protected during storage, transportation, and outdoor exposure. Furthermore, the coating seals out moisture and water, helping prevent rust formation even in demanding environments such as coastal areas and refrigeration facilities.

Benefits
CRC SP 400 helps protect valuable equipment and metal components against rust during storage and transportation. In addition, the wax coating withstands moisture, salt water, and severe outdoor conditions without becoming brittle. Consequently, maintenance costs decrease while equipment life increases. Moreover, the removable protective film allows easy cleaning before equipment is placed into service.
Applications
CRC SP 400 is ideal for long-term outdoor corrosion protection, overseas transport, seasonal equipment storage, ferrous metals, industrial machinery, steel structures, marine equipment, construction equipment, automotive parts, spare parts, pipelines, refrigeration plants, wire ropes, tools, and metal assemblies exposed to humid or corrosive environments.
How to Use
First, clean and dry the metal surface thoroughly before application. Next, apply CRC SP 400 evenly using suitable spraying or coating equipment to create a continuous protective film. Afterwards, allow the coating to dry completely before handling or storing the equipment. If necessary, adjust the coating thickness using petroleum solvents according to the required level of protection. Remove the protective film before equipment operation if required.
Overall, CRC SP 400 provides dependable long-term corrosion protection by creating a durable wax barrier against moisture and salt exposure. Therefore, it is an ideal solution for protecting industrial equipment, metal components, and machinery during storage, transportation, and outdoor service.
