Peak-ZM (zirconia and metal) primer is specifically designed to provide high adhesion between zirconia and metal surfaces and the luting material. It contains the MDP monomer and has been shown to increase bond strengths 5 times compared to using a resin cement alone. Convenient syringe and bottle delivery options. High bond strengths with resin cements. Strong bond strengths to zirconia, alumina, and metal restorations.
