International. Chemetall, an expert in metal surface pretreatment, has presented Viant, a new process that combines conversion coating in a single layer to protect steel against corrosion.
This solution, applicable in various industries (such as agriculture, construction and earthmoving) is easy to use and provides reliable corrosion protection for edges and internal surfaces.
It does not require high voltage, special equipment or constant temperature during the stages of the painting process. On the contrary, Viant can shorten the process, save resources and reduce management costs.
The new painting technology can offer decisive advantages: at the top of the list are potential savings in electricity costs and optimized processes in several areas, which can be achieved by combining pretreatment and primer in an immersion bath where neither cooling nor heating is required.
Consequently, constant monitoring of the bath temperature is also not necessary.
The film can be applied directly to the steel surface. The coating liquid film is formed by the release of ions from the metal surface rather than the active application of electricity.
Due to the wide operating temperature range and very low liquor circulation, the process is very stable and less electricity is needed to power the smaller circulation pumps.
In addition, the liquor circulation can be turned off between shifts without damaging the coating chemical. In addition to saving electricity, water and chemicals, it can also reduce the amount of wastewater that needs to be treated. All this is possible thanks to the absence of a dedicated conversion stage.
In addition to the ACE industry, where coating internal surfaces with the same thickness and the same level of protection as the exterior is a possible advantage, Viant can be suitable for many sectors where metals must be protected, such as in the following industries: manufacture of household appliances, automotive components, foundry, electrical panels, furniture, heating systems, ventilation and air conditioning, sports equipment and trailers.
