OptiBond™ Universal is a new, single bottle bonding agent that combines the reliability of patented OptiBond GPDM technology with the ease of use of a universal solution. It ensures bond strength to all surfaces and substrates, in any etching technique. The gold standard in adhesion. The proven OptiBond GPDM monomer provides more effective and reliable adhesion than other adhesive monomers to both the tooth structure and the resin material. It contains both an acidic phosphate group to effectively anchor the adhesive to the hydrophilic surface of the tooth and more methacrylate functional groups than other adhesive monomers (i.e. MDP) for a more effective interface with the hydrophobic resin. This creates better compatibility with both substrates and an overall higher bond strength. Three solvents in one – water, acetone, ethanol. To add reliability and reduce technique sensitivity, the OptiBond Universal formula is enriched with the Kerr Proprietary Ternary Solvent System.
