Epoxy Adhesive for Structural Bonding

DEVCON 14278 is a two-part epoxy adhesive supplied in a dual-cartridge tube with a 1:1 mix ratio. It cures at ambient temperature to a durable gray finish suitable for interior and exterior repairs. The formulation bonds ceramic, concrete, metal, plastic and wood without shrinking. Low odor and zero VOC content make it practical for enclosed workspaces.

30-Hour Working Time Defines the Job

The adhesive provides a 30-hour cure window at room temperature, giving ample time to position and clamp large or complex assemblies. This long open time is the key specification that determines whether the product fits the repair schedule. Faster-setting epoxies will not allow the same adjustment period, while slower systems delay handling strength.

Dual-Cartridge Dispensing Requires Matching

The dual-cartridge design delivers resin and hardener in the correct proportion only when used with the compatible 14280 applicator and 14285 mixer tip. Without these components the 1:1 ratio cannot be guaranteed and the bond may fail. No mixing tools are included in the tube package, so buyers must source the applicator and tips separately before starting the job.

Questions about this item

What does the 1:01 mix ratio mean when I’m actually using the dual-cartridge?

The resin and hardener flow in equal volume from the dual-cartridge, so you simply dispense and mix without measuring separate parts.

How does the ambient cure method limit working time and full strength?

You have about 30 hours at room temperature before the epoxy sets, and it reaches full cured properties without heat or UV exposure.

Will the 50 mL dual-cartridge fit my existing applicator gun?

It requires the compatible 14280 applicator and 14285 mixer tip; standard single-tube guns will not accept the dual-cartridge.
