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.
