The thin-film conversion coating provides superior paint adhesion and corrosion protection, while reducing environmental impact. It is suitable for multi-metal conversion steel, zinc, aluminium and can be applied using dip and spray methods. Zirconate Coating Process Zirconate coatings represent the ultimate in metal coating processing using the benefits of nano technology to create beautiful, hard-wearing, long-lasting and flexible finishes. Before Zirconate coating it is essential that the metal surface is carefully prepared to remove all contaminants and allow the coating to create a permanent bond with the metal. These products represent an environmentally-friendly alternative to iron phosphate used on steel, zinc and aluminium surfaces; and a phosphate-free substitute for zinc phosphating.

Do not let corrosion affect your business efficiency Prev Next Temporary Corrosion Protection Corrosion on your newly manufactured products or even during production can have a serious impact on the efficiency of your business. To prevent this it is necessary to use corrosion protection that forms a barrier between the metal substrate and the corrosive elements in the environment e.

Temporary corrosion protection may also perform other functions, such as lubrication or cleaning. Temporary Corrosion Protection Explained Corrosion is the gradual destruction of materials mostly metals as they are converted, through chemical or electrochemical reaction with their environment, into a more chemically stable form. Corrosion can occur in many forms: Brown rust on steel is the most well-known one.

This process is heavily influenced by environmental circumstances such as oxygen, humidity and temperature. As corrosion is a gradual process, it occurs in different phases. This can happen in a pretreatment line between the subsequent cleaning and surface treatment steps. If the circumstances do not change, corrosion will continue until the object is fully deteriorated. To prevent corrosion it is necessary to apply corrosion protection; this prevents the chemical and electrochemical processes from taking place by forming a barrier between the metal substrate and the environmental elements that are causing the corrosion.

There are two main categories of corrosion protection: permanent corrosion protection and temporary corrosion protection. The first group consists of all methods for protecting the substrate for at least its intended service life. This can include paint, powder coating, anodising in the case of aluminium and galvanising.

The second group includes all technologies that provide a temporary protective layer during the production process or transport and warehousing. Application Fields of Temporary Corrosion Protection Interoperational Corrosion Protection In-process Protection Flash rust must be avoided after cleaning metal parts in a production process.

To achieve this it is necessary to consider a range of variables such as the time between the different stages, the pH of the previous stage, application methods immersion, spray, manual , removability of the protector in the next stage, water quality and so on.

The Henkel technical service team can work with customers to help find the right solution that fits perfectly with the application. Transport Here too the environmental circumstances in which the products are being kept are crucial for temporary corrosion protection. The challenge, however, is that these conditions change frequently while goods are being transported.

Humidity, the amount of salt especialy for goods transported by sea , temperature and so on can vary widely over a single journey. BONDERITE offers a complete portfolio of temporary corrosion protectors that can provide reliable protection under these changing conditions and compatibility with corrosion protection products, such as VCI technologies volatile corrosion inhibitor.

Each is designed for a specific function; together they offer customers the corrosion protection they need throughout their processing and continuing through transport and storage to ensure that products can be delivered to end users in perfect condition.

They provide manufacturing benefits to customers through simplified coating processes and improved corrosion resistance. This provides customers with higher value products while meeting the stringent environmental requirements of today and tomorrow.
