GC adhesive technology

Abstract

GC has a successful history in developing numerous glass ionomer cements with selfadhesive properties, based on original technologies. In recent years, in the field of adhesive resins, GC has examined 4-MET from the viewpoint of adhesion theory as it relates to glass ionomer cements. Research found that 4-MET dissolves in water, which in turn, led to the development of the world's first self-etching primer utilizing 4-MET in an aqueous solution. Based on this technique, GC has developed “UniFil Bond”, “LINKMAX”, and “UniFil Core” in rapid succession, and now has succeeded in developing “G-BOND”, a one-bottle, one-step typed bonding agent. The development of G-BOND was based on the concepts of easy handling through a perfect one-bottle, one-step system, producing the same bond strength as two step systems and excellent storage stability. The result is that the application time of G-BOND is the shortest among commercially available bonding agents, while the micro-tensile bond strength is almost same as that of UniFil Bond. In this article we review GC adhesive technology focusing on adhesive resins.
