SurTec shows portfolio for temporary corrosion protection at Parts2clean 2022

Corrosion protection is one of the permanent topics in surface coating - because metallic components must be optimally protected against corrosion not only during the manufacturing process, but also during transport and temporary storage between production steps. At the same time, the requirements for quality and environmental compatibility of the products used have increased significantly. At Parts2clean 2022, surface technology specialist SurTec will showcase its comprehensive portfolio of temporary corrosion protection agents (Hall 4, Booth C11). In two presentations, SurTec will also provide theoretical and practical background information on the topic of temporary corrosion protection. In the technical forum, Maximilian Frisch, Chemical Engineer at SurTec, will speak on the topic of "Temporary Corrosion Protection and Methods for Testing". While this talk refers to the scientific background, Nicole Völler, Global Project Engineer Industrial Parts Cleaning at SurTec, presents the concrete application with SurTec 537 as an innovation in the field of aqueous corrosion protection.

"There are a number of reasons why the demands for temporary corrosion protection are growing," explains Maximilian Frisch. "One important aspect, for example, is that climatic conditions have changed and today high humidity and heat can occur almost all year round, even in Europe. In addition, there are growing requirements regarding freedom from stains, which is monitored via automatic camera systems for quality control. Against the backdrop of rising energy prices, there has also been an increased demand for wet corrosion protection in order to dispense with energy-intensive drying of components wherever possible." Among the most important requirements for temporary corrosion protection is ensuring trouble-free heat treatment, especially also in thermodiffusion processes. Low feed concentrations are generally required, as well as freedom from phosphorus, silicon and fluorine, especially in high-purity applications. The multimetal capability of the corrosion inhibitor is also important, since production is often carried out in mixed processes. Similarly, the product must be stable in the various applications, for example spraying, high pressure, ultrasonic, CNP, PPC, etc. In addition, depending on the application, there are specific requirements such as, in particular, freedom from foam or, in the case of robot-assisted cleaning processes, protection against corrosion even in the vapor phase.
