Fast Set Extreme

Old Soldiers Home

Bonstone Fast Set Extreme is a knifegrade (non-sag) exterior epoxy system is suggested for fast setting or cold weather applications where initial setting speed or use in cold temperatures is critical. Unlike most epoxies, Fast-Set™ cures at below freezing temperatures.

The cartridge system eliminates measuring and mixing the two components. Bonstone Fast Set Extreme is easy to use and great for assembly line epoxy fabrication. Use either adapter or our Cartridge Gun to dispense.

Not recommended for interior application-strong odor when applying.
