He who rests, rusts? In most cases, the long-term storage of metal components is used to keep spare parts in stock for a period of up to 15 years. Such a period requires different measures for corrosion protection than preservation for a manageable transport period of a few weeks. This is because the longer metals are exposed to environmental conditions, the higher the probability of corrosion.
Due to the usually large number of parts stored, the economic risk is also higher. To avoid damage and returns, EXCOR Corrosion Research develops suitable, reliable corrosion protection concepts for the long-term storage of your metal parts.
‘Excor has proven to be a reliable partner for long-term storage. We particularly appreciate the in-depth advice that has been tailored to our specific requirements. The collaboration helps us to protect our components from corrosion in the long term.’

Our expertise for your products
Our many years of experience in the field of corrosion protection enable us to develop the right solution for every storage environment and duration.
Particular attention is paid to the careful selection of corrosion protection agents and the correct implementation of the packaging process, especially for corrosion-critical long-term storage. Our team of experts will find the optimum corrosion protection for your storage conditions.
Packaging measures for long-term storage
- Testing the parts for surface residues from previous processes
Residues from the mechanical machining processes or grease residues from cleaning baths can have a corrosive effect on the one hand and on the other hand hinder access for VCI or ICB agents. A chemical analysis of the parts surface is therefore necessary.
- Hermetically enclose the packaging unit with a sealed barrier film
e.g. with a box cover made of aluminium foil as a container liner
- Fixing the individual components in the packaging
e.g. by using compartments made of hollow chamber plates with VCI or ICB or by using corrosion protection bags made of bubble wrap to prevent mechanical damage during transport.
- Use VCI/ICB carriers rich in active ingredients
e.g. by using a thicker film or hollow chamber material
- Addition of desiccants
These dehumidify the sealed-in air.
- Testing the stackability
Depending on the storage conditions, this can be a criterion.
- Testing a prototype of the packaging
The packaged product should be loaded in an EXCOR climate chamber using data loggers (which can be read from the outside) in order to recognise any weak points in the packaging.
