G-BOND is a new, revolutionary 7th Generation (single component) adhesive that takes the guesswork out of bonding. The unique combination of Phosphoric Acid Ester Monomer and 4-MET Adhesive Technology creates superior etch and adhesion to enamel, in addition to providing a chemical and mechanical seal to dentin (referred to as the Nano Interaction Zone). Its features are, 4-MET Monomer, Phospohoric Acid Ester Monomer, Minimal decalcification; almost no exposure to collagen fibers, This "nano" level reaction produces an insoluble calcium compound for a better bond.5% filler seals tubules leads to fewer voids between the thin adhesive layer and the dentin, which minimizes microleakage and prevents microbial invasion.
