The Importance of Rust Prevention in Storage

rust prevention

Anything in prolonged storage, especially if made of metal, will always increase the likelihood of storage corrosion. The best prevention for this is to minimise storage time. Proper storage limits the collection of water due to rain, snow, and condensation on panel surfaces.

Under roof storage is naturally the best type of storage and the most preferred. Should metal be stored for a prolonged period out of necessity, the material should be stored in a level area out of the way of other activities and metals to minimise the number of movements required. This also lessens the chances of metal bumping or grinding on other metal.

Deterioration due to rusting and corrosion of metal materials, parts, and components during storage is a persistent problem in any industry. It causes direct and indirect material losses. Corrosion of materials may cause time to be diverted to handling customer complaints and delayed deliveries due to the reworking of corroded components.

Planning for rust prevention and protective coating before any storage takes place is a sound strategy to minimise material losses.

Preventive Storage Corrosive Deterioration

Desiccants to control air humidity may be used to prevent corrosive deterioration during storage. Molecular sieves and silica gels can be used as desiccants to absorb excess air moisture. For extreme measures, sealed films of high-pressure polyethylene and special waterproof and airproof packing systems may be used for critical metal materials and equipment.

Moisture-barrier bags or VCI plastic may also be used for packing important components, critical parts, and equipment.

All these provide rust protection against moisture, humidity, salt, acidic contaminants, and oxygen. The concept of all this is to ensure that the storage space – usually a warehouse – is somewhat sealed in a favourable environment to ensure complete protection while in storage.

Creating a Protective Coating Barrier During Storage

Another method of rust protection and corrosion prevention for metal materials, parts, components, and equipment is to apply a protective coating. This acts as a barrier to prevent or break up the elements that cause corrosion.

The selection of appropriate protective coating is based on:

  • The type of metal for protection and for how long the protection.
  • The ambient conditions and the type of environment in the warehouse.
  • Feasible application method and removal for subsequent processing.
  • Requirements regarding safety, fire risk, and waste disposal.

Based on the above, it is safe to say that when it comes to protective coating for rust prevention and protection during warehouse storage, the best coating to use is Unituff 452.

Unituff 452 is a polyvinyl chloride copolymer solution coating for external applications as a heavy-duty membrane against rust-causing components such as moisture. It is safe to use, easily peels off, flexible, and easily applied. Visit Unituff at https://unituffglobal.com/ for more details.
