Wax Corrosion Inhibitors

Wax Corrosion Inhibitors and Protective Coatings

Many metallic parts and components produced by the manufacturing industries may have bare metal surfaces which require to be protected until brought into use. They may be finished metallic parts, which need to receive some form of protection from corrosion during shipping or storage, or they may require some form of protection from corrosion whilst in use. Typical examples are automotive parts, steel strip or steel sections which may require protection for a few days due to a delay in the manufacture and supply schedule.

In some cases, the parts may need to be protected after machining.

A Temporary Corrosion Protection Product is a material that can be easily removed from the metal surface after treatment. It is not designed to be permanent, or difficult to remove in the same way as a paint system or plastic coating. The material may need to provide protection when exposed to a variety of differing corrosive atmospheres, indoors, outdoors either under cover or fully exposed, in a marine environment and under effects of direct sunlight

During its protective period, it needs to give adequate freedom from corrosion of bare metal surfaces for a predetermined length of time in manufacture, assembly, storage or distribution.

The uses and applications for Temporary Protectives include the following:

• Steel and coated steel strip
• Steel profiles, sections and tubes
• Aluminium or other alloy strip and sections
• Machined parts and components
• Tools and machine tools in manufacture or storage
• Fasteners such as screws, rivets, bolts, etc
• Machinery parts, either finished or for later assembly
• Automotive components and sub-components
• Electrical parts and assemblies
• Agricultural parts and machinery

The wax like protectives tend to be specified where consumers are seeking a soft heavy build film. They are particularly used for core protection of wire ropes, cables, and chains, where flexing will not result in breakage of the protective film.

Volatile Corrosion Inhibitors:

Usually abbreviated to VCI

Whilst mainly used for protecting steel surfaces, products are now available for protecting other metals, and for multi-metal situations. VCI products work by continuously releasing a vapour with powerful anti corrosion properties.
