Press release submitted on behalf of hubergroup.
hubergroup Chemicals, Rolling Meadows, Illinois, a manufacturer in the chemical sector, offering a broad product portfolio of speciality chemicals, including resins, pigments and concentrates, UV-monomers, UV-oligomers and additives, introduced 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.
Combining synergist and binder functionality
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.
Optimized for coating and varnish systems
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 behavior.
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.
Key features of UHVPI-222200 include:
• Very high reactivity, even at low addition levels
• Supports faster curing, shorter production cycles and energy-efficient processing
• Low viscosity and good pigment wetting
• Reliable surface cure and high gloss
• Effective reduction of oxygen inhibition in thin films
• Suitability for low-migration and food-packaging applications
UHVPI-222200 is designed for a broad range of energy-curable applications, with a strong focus on high-performance coating and varnish systems.
