Quick-Set Epoxy Structural Adhesives
For quick repairs, these epoxies begin to harden in 6 minutes or less. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives.
The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
HY4090 is a blend of epoxy and instant-bond adhesive for a balance of strength, cure speed, and temperature resistance.
50132 works especially well on plastics and composites.
