GC G-BOND:
One Component, One Coat Bonding System for Light-Cured Composites
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 chemical and mechanical seal to dentin – referred to as the Nano Interaction Zone.
Etch, desensitize, prime and bond in as little as 20 seconds. Ideal for bonding light- cured composites, compomers and dual-cured cements and core build-up materials (light-cure mode) to tooth structure.

Features & Benefits:
Fast and Easy Application
Just brush G-BOND onto the tooth’s bonding surface, wait
5 to 10 seconds, then air thin with high pressure syringe air and light-cure for 10 seconds. For almost any application, in as little as 20-30 seconds and you’re good to go.
No Guesswork – Simple Technique
New G-BOND takes the guesswork out of bonding. It’s not technique sensitive like other “all in one” bonding systems so you don’t need to worry about “how dry” or “how wet” or how “over-etched” or how “under-etched” the tooth surface is. It’s not cumbersome like two and three component systems. There’s no “lollipop” or “bottle-squeezing” delivery systems or “impregnated” brushes to work with. G-BOND gives you clinically successful results time after time. It’s a simple technique: one coat, air thin and light-cure.
No Post-Op Sensitivity
One component, self-etching G-BOND virtually eliminates post operative sensitivity because the dentin tubules are never exposed. G-BOND’s 5% filler further seals the tubules and decreases pulpal sensitivity. There are fewer voids between the thin adhesive layer and the dentin which minimizes microleakage and prevents microbial invasion.
Strong, Reliable, Consistent Bond
Dry, moist or wet, dentin or enamel, G-BOND produces a strong, reliable, consistent bond.
- 4-MET monomer provides consistent bond strength to dentin
- Phosphoric Acid Ester Monomer provides consistent bond strength to enamel
G-BOND’s “Nano Interaction Zone” Technology, an advanced formulation of Phosphoric Acid Ester Monomer, 4-MET Monomer, nanofilled particles, and acetone and water solvent, decalcifies the tooth, provides a wetting property, diffuses monomer into the tooth structure, then polymerizes and hardens when light-cured and creates an ionic bond with the apatite in the tooth structure.
Nano Interaction Technology
G-BOND forms a non-conventional interface with the dentin – a “Nano Interaction Zone” (NIZ) with minimal decalcification and almost no exposure to collagen fibers.
This “nano” level reaction produces an insoluble calcium compound for a better bond less likely to deteriorate from enzymes contained in the mouth.
Remarkably Thin Bonding Layer
G-BOND’s Nano Interaction Technology creates a remarkably thin (less than 300
nanometers) bonding layer that offers many advantages:
- Easy clean-up and removal of adhesive overflow
- Completely coats all bonding surfaces even in an extremely shallow cavity - fewer voids
- High surface tension makes it apply readily and stay put on all bonding surfaces
- Bonding layer is not visible
Stable Material, Simple Storage
- Store at room temperature
- 2-year shelf life
Cap should be replaced immediately after use. If not in use for prolonged periods, store in refrigerator.
