Porcelain bonding agent and conditioner. Cerinate Prime is a one-bottle, no-mix organosilane ceramic primer that increases and enhances bond between composite resin and porcelain. Porcelain Conditioner is a citric acid pretreatment that activates and hydrolyzes Cerinate Prime. Use of Porcelain Conditioner as a pretreatment, combined with the use of silane ceramic primer, improves the durability of the porcelain composite resin bond, both in the bonding of all-ceramic restorations and for porcelain repair.
