Sustainable painting processes

Surfaces of railway vehicles have to withstand many chemical and mechanical stresses..

Painting processes play a key role in the sustainable and economical production of rail vehicles. With its "SnapCure" paint technology, the global paint manufacturer Mankiewicz is introducing a product to the market which significantly shortens the process time and makes energy-intensive oven drying obsolete. The drying times of paints in particular currently pose some time-related challenges for rolling stock manufacturers and their suppliers. Clear coats in particular have a comparatively long drying time. Compared to the usual drying time of eight to twelve hours on the market, the ALEXIT® SnapCure Clearcoat dries in just two hours at room temperature. This eliminates the need for costly and energy-intensive oven drying, which makes a valuable contribution to the ecological footprint of manufacturers. There is another point in terms of sustainability: the coating system has a high solids content, so that fewer solvents are emitted. Furthermore, it is free from diisocyanates, which helps to protect employees. Thanks to the patented paint formulation, the technology also allows the independent adjustment of processing parameters such as pot life and drying time for the requirements of the railway industry. This ensures reliable and efficient application in line with the specific process conditions in the rail sector. The service life of railway vehicles often exceeds 15 years. Accordingly, materials in the interior or exterior must be able to withstand numerous influences. The outer skin of trains in particular is subjected to high stresses such as weather influences, stone chipping or chemical components. Paint not only plays a central role as an essential surface protection, but also ensures the feel-good factor for passengers by maintaining the value of the coating. ALEXIT® SnapCure is extremely resistant to chemicals and UV radiation. Overall, the coating system therefore fulfils all the requirements of the rail industry and brings considerable efficiency to the painting process of rail vehicles.
