PL-7121 is a novel low-shrink urethane monomer based on Esstech's proprietary methacrylate technology. PL-7121 possesses a volumetric shrinkage of 2.0 - 2.5% and conversion of 65 - 80% without filler. PL-7121 has very low color and can be added to formulations to add toughness. PL-7121 possess the excellent combination of superior elongation and strength.
