Bond Plus NT is a dental adhesive that contains 15% barium glass filler, which is 0.4 microns in size. This unique technology provides excellent protection against microleakage and high bond strengths to a variety of surfaces. The filler reinforces the hybrid zone and penetrates the dentin tubules, creating a true "structural bond" not found in unfilled nor "nano" filled adhesives. Bond Plus NT carries adhesion promoters in an ethanol solvent, which eliminates the need for multiple coats and constant re-application commonly found with acetone adhesives. It can be used for both direct and indirect bonding applications.
