LAROMER® PO 9103 is an oligomeric amine modified acrylate showing outstanding reactivity combined with high gloss. It is preferably used as combination resin to accelerate reactivity of UV-coatings and inks. LAROMER® PO 9103 is fully compatible with all mono- and multifunctional monomers and all common oligomers like epoxy, polyester and urethane acrylates. LAROMER® PO 9103 forms hydrophobic surfaces after UV/EB curing resulting in excellent solvent fastness with high MEK and acetone resistance. Apart from that it provides excellent adhesion properties on plastics like PET, PC and ABS making it a valuable building block for all radiation curable formulations in graphic arts and wood coatings, where adhesion on plastics is essential. Due to its amine modification LAROMER® PO 9103 imparts very high reactivity when combined with H-abstraction type II photoinitiators. It also considerably enhances the reactivity of type I photoinitiators overcoming effectively oxygen inhibition in the surface curing of thin films.
