In times of climate change, the reduction of harmful emissions is of growing importance, not only in public discussion, but especially in the industry. Requirements, standards and regulations exist in various countries of the European Union and worldwide. They ensure proper and safe operations and are intended to reduce negative effects on people and the environment.
Foundry chemistry has a significant influence on the emission load in the foundry. In general, it is necessary to distinguish between VOCs (volatile components) and BTX (decomposition products).
To comply with emission limits and maintain production permits, foundries must find effective ways to reduce emissions throughout their operations.
One strategy is to use 100% zero-emission inorganic binders such as INOTEC technology. This strategy has proven to be particularly effective in low-pressure and gravity die-cast aluminum applications such as the manufacturing g of cylinder heads and crankcases.
In the area of cold box binders, ASK Chemicals follows a holistic approach to reduce emissions. It takes into account not only the solvents, but also the actual resin components of the cold box formulation. R&D studies show that the resin components have a significantly greater influence on emissions in operations than the solvents. The result of this approach is a highly efficient binder technology that increases productivity and achieves significant emission reductions by lowering binder and amine levels while maintaining the same application properties.
The latest development in the field of highly efficient cold box binders is ECOCURE BLUE PRO. The newly developed PUR cold box system optimizes casting properties and at the same time reduces binder and amine consumption. With this additional increase in efficiency, it helps foundries to further improve their emissions and environmental performance, notably reducing BTX emissions and VOCs.
