BISCO’s Primers are developed to be used with a multitude of restorative substrates and composite resin cements. BISCO’s primers are used to enhance the bond strengths unlike many other surface primers currently on the market. PORCELAIN PRIMER and BIS-SILANE™ are silane-based primers specifically design to treat silica-based ceramics. Z-PRIME PLUS™ is the first dedicated product for bonding metal oxide ceramics such as Zirconia and Alumina restorations. When using BISCO’s primers, you are guaranteed enhanced bond strengths, a simplified application process, and longevity with all your indirect bonded restorations.
