UVS-Series

High-performance UV-curable oligomers for advanced coatings.
Optimized for low viscosity, fast curing, and excellent adhesion on various substrates.

UVS Series – Advanced Photosensitizers for Efficient UV Curing

UVS Series products are advanced photosensitizers developed to enhance the performance of UV-curable systems. By efficiently absorbing long-wave UV light and transferring energy to photoinitiators, they enable faster curing, improved depth penetration, and enhanced end-use properties. Suitable for both cationic and radical polymerization, these specialty additives are key to achieving optimal results in demanding UV applications.

As a globally active supplier, NAGASE offers the UVS Series with reliable availability and technical support for formulation development in coatings, inks, and adhesives.

Product Varieties

Beside a main UVS-photosensitizer there are several sensitizers under development with other substituents instead of alkyls or with sensitivity to UV light of even longer wavelengths. Some of them can be used as co-photosensitizers, maximizing the performance of the main one, increasing transmissibility and compatibility, further maximizing efficacy of photoinitiator and improving the yellowing.
