Applications

The success of the UV technology is based on the perfect coordination between the radiation properties of the UV source and the specific requirements of the UV application. Both, in UV curing  as well as in the area of water treatment, substrate or liquid radiation is highly dependent on the spatial dispersion of UV light in the irradiated area or volume through which the substrate or liquid passes.

The UV energy (UV dose) is therefore determined by the geometric characteristics of the reactor and the optical properties of the reflector and/or the UV transmission of the liquid. A typical feature is the linear connection between an increase in the speed of a process and the resulting UV energy demand. In the case of UV modulation, the energy additionally depends on the moment the substrate passes the lamp.

UV TECHNOLOGY FOR A VARIETY OF APPLICATIONS

In UV curing, specially formulated inks and varnishes are dried or cured within a fraction of a second – their constituents polymerize or cross-link. UV inks consist of oligomers, monomers, photo initiators and, in contrast with conventional inks and varnishes, do not require any solvents or thinners (that evaporate or absorb slowly) for the drying process. This is one of the reasons UV technology is so environmentally friendly.UV curing systems as complete systems or components are manufactured for the areas of printing, coating, adhesion and inkjet. Our lamps and electronic ballasts are used in the systems of IST, a leading company in the UV technology sector.
