GC G-BOND One-Component Light-Cure Adhesive — Single-Coat Bonding System

G-BOND is a next-generation, single-component, self-etching light-cure adhesive designed to simplify and streamline bonding procedures. Its advanced formula combines phosphoric acid ester monomers with 4-MET adhesive technology to deliver strong, consistent adhesion to both enamel and dentin while creating a stable nano-interaction zone (NIZ) at the tooth interface. This ensures a secure chemical and micromechanical seal without exposing dentin tubules, effectively reducing the risk of postoperative sensitivity. G-BOND can be applied in one coat and light-cured in seconds — offering a fast, reliable, and low-technique-sensitivity solution for bonding composites, compomers, and dual-cure core materials.

Key Features & Benefits

• Single-component, one-coat adhesive for simplified application and reduced steps. 
  
• Self-etching formulation bonds reliably to enamel and dentin without a separate etch step. 
  
• Creates a chemical + micromechanical seal via a “Nano Interaction Zone,” enhancing bond durability and minimizing marginal leakage. 
  
• Light-cure activation allows for precise control and rapid setting — efficient for busy clinical workflows. 
  
• Low postoperative sensitivity and reduced risk of marginal staining or discoloration. 
  
• Compatible with light-cured composites, compomers, and dual-cure core build-up materials when used in light-cure mode. 
  

Typical Uses

Ideal for direct composite restorations, compomer restorations, core build-ups, and other light-cure or dual-cure restorative procedures. Its ease of use and reliable bond make it suitable for both anterior and posterior cases.
