Trimethylolpropane ethoxy triacrylate (TMPEOTA) is a reactive diluent commonly used in ultraviolet light (UV) and electron beam (EB) energy curable coatings and inks. TMPEOTA can be used to impart crosslinking to energy curable coatings and inks while maintaining a degree of flexibility and toughness. Of the common triacrylate diluents used in energy curable formulations, TMPEOTA exhibits the highest reactivity and the greatest viscosity reduction of oligomers.

Isobornyl acrylate (IBOA) is a monofunctional reactive diluent that polymerizes when exposed to sources of free radicals. The bicyclic structure of IBOA gives rise to polymers of increased Tg, while its monofunctionality minimizes crosslinking to provide coatings and inks with good hardness and resiliency combined with flexibility and impact resistance.
