hubergroup Chemicals has introduced UHVPI-222200, an amine-modified polyether acrylate oligomer engineered to enhance curing speed, improve process efficiency, and deliver superior surface quality in next-generation UV-curing coatings.

 

A standout feature of UHVPI-222200 is its exceptionally high reactivity—even at low addition levels. The performance boost enables faster curing, shorter production cycles, and lower energy consumption during UV-curing processes. At the same time, its low viscosity provides excellent flow behaviour and greater flexibility in formulation.

 

UHVPI-222200 acts as a highly efficient amine synergist for Norrish Type II photoinitiators, including benzophenone- and thioxanthone-based systems, while also supporting Type I photoinitiators, as per the speciality chemicals major.

 

By accelerating surface radical formation, the oligomer significantly reduces oxygen inhibition—an issue commonly encountered in thin films and pigmented systems. The result is a reliable surface cure with high gloss and an improved surface finish.

 

Thanks to its high reactivity and low viscosity, UHVPI-222200 can function both as a synergist and as a reactive binder. In highly reactive, low-viscosity formulations such as UV varnishes and coatings, it can even serve as the primary—or sole—binder. This capability simplifies formulations, reduces monomer content, and supports stable processing.

 

With a TMPTA (Trimethylolpropane triacrylate) content of less than 0.1%, the product is particularly suited for low-migration applications. Typical end uses include industrial coatings, UV varnishes, wood coatings, and other energy-curable systems, as well as UV flexo inks and overprint varnishes (OPVs).

 

Key features of UHVPI-222200: 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; and effective reduction of oxygen inhibition in thin films.
