hubergroup Chemicals has launched UHVPI-222200, an amine-modified Polyether Acrylate Oligomer designed to significantly improve curing performance, process efficiency, and surface quality in modern UV-curing coatings.
According to the company, 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 behavior and formulation flexibility.
UHVPI-222200 functions as an 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 reduces oxygen inhibition, particularly in thin films and pigmented systems.
Due to its 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 behavior.
With a TMPTA (Trimethylolpropane triacrylate) content of less than 0.1%, UHVPI-222200 is 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.
