Hubergroup launches UV-curing oligomer

Hubergroup Chemicals has introduced UHVPI-222200, an amine-modified polyether acrylate oligomer designed to improve curing performance, process efficiency and surface quality in UV-curing coatings.

A key characteristic of the product is its high reactivity at low addition levels, enabling faster curing, shorter production cycles and reduced energy consumption. Its low viscosity provides flow behavior and formulation flexibility.

UHVPI-222200 functions as both an amine synergist and a reactive binder. It is compatible with Norrish Type II photoinitiators, including benzophenone- and thioxanthone-based systems, as well as Type I photoinitiators. By accelerating surface radical formation, it reduces oxygen inhibition in thin films and pigmented systems, delivering reliable surface cure with high gloss.

In highly reactive, low-viscosity systems such as UV varnishes and coatings, the product can serve as the main or sole binder, supporting simplified formulations and reduced monomer content. With a TMPTA content of less than 0.1 percent, it is suited for low-migration applications, including food packaging.

Typical end uses include industrial coatings, UV varnishes, wood coatings, UV flexo inks and overprint varnishes across energy-curable coating and varnish systems.
