Prime&Bond active

Moisture levels vary.

Our bond won't.

Prime&Bond active provides

  • Versatility for use with all etching methods, all indications
  • Reliable performance on over-wet and over-dried dentin
  • Virtually no post-operative sensitivity
  • Low film thickness for a reduced risk of pooling and misfit of the restoration
  • A relaxed working time and reduced waste, remaining usable for 30 minutes in a closed CliXdish
  • High initial bond strength with Calibra Ceram cement for indirect restorations
  • A patented formulation free of HEMA, TGDMA, or bisphenol

Active Control for Reliable Restorations

Prime&Bond active introduces the new, patented Active-Guard Technology. - Our formulation provides well balanced hydrophobic and hydrophilic properties to ensure complete coverage and penetration at varying moisture levels. So even if dentin is overly wet or dry, you get a reliable bond that actively guards against the leading causes of adhesive failure.

Active Moisture Control


Most adhesives are comparatively hydrophobic, tending to separate from water. With too much water on the prepared surface, the adhesive can’t achieve uniform coverage, leaving gaps that may weaken the bond and may cause post-operative sensitivity. If dentin is overly dried, collagen fibers can collapse and prevent effective sealing.

Prime&Bond active overcomes the surface tension of water and spreads across dentin 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.

Prime&Bond active

To ensure a homogeneous application, water and solvent evaporate together, leaving an even, consistent adhesive layer.

Scotchbond™ Universal

Cannot overcome the surface tension of water. Adhesive and water remain separated.

iBOND® Universal

Cannot overcome the surface tension of water. Adhesive and water remain separated.

Active Cavity Spreading

COMPLETE COVERAGE Inherent surface tension prevents other adhesives from spreading easily across the surface of the cavity. Dry spots that remain unbonded can weaken the restoration and may lead to post-operative sensitivity and microleakage. Prime&Bond active is formulated to spread actively, minimizing the risk of inadvertently leaving dry spots.

Prime&Bond active

A single drop, placed using a micro brush without further manipulation, naturally spreads across most of the surface.

Scotchbond™ Universal

Other universal adhesives resist spreading.

iBOND® Universal

Other universal adhesives resist spreading.

Low Film Thickness

Thick adhesives can have a tendency to pool in the corners of the proximal box of a Class II restoration. These adhesive pools can show up as translucent areas on a radiograph, which can easily be misdiagnosed as a void, gap, or secondary decay, leading to unnecessary replacement. Thicker adhesives may also change crown prep geometry, impacting crown fit. Prime&Bond active self-levels to actively create a thin, uniform adhesive layer.
