Medium Viscosity, Long Pot Life Epoxy Bonding Adhesive
Purpose:
Slow-Bond 6500 is a two-component, solvent-free, moisture insensitive, 100% solids epoxy resin adhesive. Designed to structurally bond fresh concrete, old concrete to old concrete, concrete to steel and for use to inhibit the corrosion of steel.
Uses:
Epoxy resin adhesive for applications where a long working time is needed.
Suggested Applications:
 | Structural bonding of fresh concrete to hardened concrete and steel |
| Grouting dowels, anchors, rebar, bolts and metal anchors |
| Structural grouting of cracks in concrete, masonry and wood |
| Structural adhesive for bonding concrete, masonry, metal and wood |
| Interior and exterior |

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.
