A key characteristic of the new hubergroup UHVPI-222200, an amine-modified Polyether Acrylate Oligomer, is its very high reactivity, even at low addition levels. This enables faster curing, supports shorter production cycles, and contributes to reduced energy consumption in UV-curing processes. At the same time, the product’s low viscosity ensures excellent flow behaviour and formulation flexibility.
UHVPI-222200 functions as a highly efficient amine synergist for Norrish Type II photoinitiators, including benzophenone and thioxanthone-based systems, while also supporting Type I photoinitiators. By accelerating surface radical formation, it effectively reduces oxygen inhibition, particularly in thin films and pigmented systems. The result is a reliable surface cure combined with high gloss and excellent surface appearance.
Thanks to its very high reactivity and low viscosity, UHVPI-222200 can be used both as a synergist and as a reactive binder. In highly reactive, low-viscosity systems, such as UV varnishes and coatings, it can also serve as the main or sole binder. This supports simplified formulations, reduced monomer content, and stable processing behaviour.
With a TMPTA (Trimethylolpropane triacrylate) content of less than 0.1%, UHVPI-222200 is particularly well suited for low-migration applications. Typical uses include industrial coatings, UV varnishes, wood coatings, and other energy-curable coating systems, as well as UV flexo inks and OPVs.
