ZirClean is a non-abrasive cleaning agent for the bonding surfaces of Zirconia following intra-oral try-in. During try-in, the phosphate in saliva forms an ionic bond with the Zirconia, and it cannot be removed by simply rinsing with water or ultrasonic cleaning. The successful removal of that ionic bond requires an alkaline solution such as Zirclean which contains potassium hydroxide. Apply ZirClean for 20 seconds to sandblasted Zirconia. Rinse and dry. Follow up by applying Z-Prime Zirconia primer and dry with air for 3-5 seconds. Available in 5g Syringe, with 30 tips included.
