Z-Prime Plus is a single-component, MDP-containing, priming agent used to enhance adhesion between indirect restorative materials and resin cements.Z-Prime Plus significantly enhances bond strengths to Zirconia, Alumina and Metal substrates due to its unique combination of two active monomers, MDP, a phosphate monomer, and BPDM, a carboxylate monomer. This combination of primers gives Z-Prime Plus a synergistic effect resulting in its high bond strengths.Z-Prime Plus 2ml bottle provides approximately 120 applications and the 4ml provides approximately 240 applications.
