New UHVPI-222200 for high performance UV curing coatings

Packaging Solutions

hubergroup Chemicals is introducing UHVPI-222200, an amine modified Polyether Acrylate Oligomer designed to significantly improve curing performance, process efficiency, and surface quality in modern UV curing coatings.

A key characteristic of UHVPI-222200 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.
