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.

EBECRYL® LED 04 is an acrylated polyamine that can be added as a co-resin to UV curable formulations. EBECRYL® LED 04 – when combined with an appropriate photo initiator system – transforms formulations into UV LED, UVA, or low energy curable systems by providing improved surface cure. In addition, this effect is also seen in high energy cure formulations. The improved surface cure is obtained by mitigating oxygen inhibition of the free radical process and/or by being an amine synergist for Norrish type II photo initiators.

EBECRYL® LED 05 is an acrylated polyamine that can be added as a co-resin to UV curable formulations. EBECRYL® LED 05 – when combined with an appropriate photo initiator system – transforms formulations into UV LED, UVA, or low energy curable systems by providing improved surface cure. In addition, this effect is also seen in high energy cure formulations. The improved surface cure is obtained by mitigating oxygen inhibition of the free radical process and/or by being an amine synergist for Norrish type II photo initiators.

β-carboxyethyl acrylate (β-CEA) is a mixture of reactive esters, each of which contain both acrylate and carboxylic acid functionality in the same molecule. Referring to the included structural formula, this mixture contains some unreacted acrylic acid (n=0), along with higher adducts of acrylic acid (n=1,2,3...). The dimer (n=1), i.e. β-CEA, is the largest single component, and the average molecular weight is equivalent to that of the dimer. β-CEA will polymerize when exposed to sources of free radicals. Because of its carboxylic acid functionality, β-CEA is useful as an adhesion promoter.
