Rahn has introduced three new UV-curable oligomers, Genomer 5142 and Genomer 5161 oligoamine and Genomer 2280 epoxy acrylate. Both oligoamines Genomer 5142 and Genomer 5161 are acrylated amine synergists for radically curable coatings, inks and adhesives. In combination with a photoinitiator type II, Genomer 5142 and Genomer 5161 improve cure speed and surface cure. The recommended concentration in formulations is typically between 5-15%. Smaller amounts can also reduce oxygen inhibition. Areas of use are wide and cover most UV/EB applications.
Genomer 2280 is a modified bisphenol A epoxyacrylate and offers a balance of properties. Compared with standard bisphenol A epoxyacrylates, Genomer 2280 features greater flexibility and toughness while maintaining fast cure response, high resistance properties and high hardness, according to the company.
