Prime&Bond active features the new, patented Active-Guard Technology. Universal adhesive with active moisture control, Prime&Bond active overcomes the surface tension of water and spreads across dentine and into dentinal tubules to form an even, homogeneous layer. Upon air-drying, the solvent and water evaporate together, leaving a consistent coating of adhesive across the entire surface to ensure a strong bond. Easy to use. Consistent results. High bond strength.
