ndustrial products have to comply with increasingly stricter quality requirements. This means that treatment methods and paint systems for finishing have to be selected with the utmost care. For this reason, NTS Finish has its own quality laboratory where products with a paint system or metallic coating can be studied and tested. These extensive research facilities are not only used within the NTS-Group, but also by a growing number of external clients. Expertise in materials and surface engineering enables NTS Finish to provide qualified advice about treatment methods and coating systems.
