Multi-Purpose, Non-Sag Anchoring and Bonding System
Purpose:
Gelbond GS is a two component, high strength structural epoxy adhesive. Gelbond GS combines a long working time of 20 minutes, while also providing an anchor that can be loaded in as little as 4 hours. Gelbond GS allows for application from 35°F to 115°F, the largest application temperature range of our epoxy products.
Suggested Applications:
 | Security caulk for detainment facilities |
| Epoxy mortar binder for concrete repair |
| Sealing of ports and cracks for epoxy injection |
| Repair of cracks in concrete or masonry |

N/A | ¹Working Time: Elapsed time at which adhesive in the nozzle begins to increase in viscosity from a flowable material to a non-movable semi-solid.
²Bolt-Up Time: Length of time required to apply the allowable load to the anchor (25% of ultimate load)
Note: Gel, working and bolt-up times lengthen as temperatures decrease and shorten as temperatures increase.
