UV systems from IST Metz are used for different working widths for 2D and 3D applications. The surface treatment of three-dimensional objects makes special demands on curing technology. We therefore offer a number of solutions for a wide variety of requirements of UV coatings – including heat-sensitive materials.

The IST Metz Group’s UV driers enable you to cure coatings of paper, films, PVC plastics as part of numerous different processes. Examples here include curing adhesives, siliconisation, matting or even hard coating. UV system technology from IST Metz is used during the application and subsequent final curing, for example, of cationic or even radically curing silicones. If radically curing silicones are used, inert gas (nitrogen) is applied to produce the right bond (oxygen-reduced operation) with the help of IST UV systems technology. The residual oxygen content under production conditions is ≤ 50 ppm. No nitrogen is required, however, when cross-linking cationically curing silicones. A post-cure effect is created after cross-linking here. This means that it is not possible to switch the coated and cured side immediately after cross-linking. When cross-linking with adhesives, adhesives are formulated especially for the particular specification on the product and cured using the UV technology from IST METZ. IST systems can also be used to achieve special effects, such as matting with microfolds on the surface. This excimer technology is used especially in PVC flooring. It goes without saying that the IST Metz portfolio of systems also offers the possibility of using UV technology in PVC flooring (we talk about pre and post-curing). UV curing varnishes, containing matting agents, are cured here. The degree of matting is determined using a UV lamp (pre-curing). The surface is then finally cured with the help of final curing. When hard coating, films are applied on a film with the help of UV curing varnishes and cured using our IST Metz UV systems. This creates an extremely scratch-resistant and durable surface.
