hubergroup Chemicals introduces 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.
Optimised 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 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.
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.
