After the recommended curing time you can test the epoxy by leaving a small amount on the mixing tray.  If the epoxy on the mixing tray is hard your project is ready to be handled.

DO NOT test the bond by moving the components to see if it has cured, this will only weaken the bond.

First you should only dispense enough to be applied within 20 mins.  Make sure you have prepared all the components before you start the mixing process.  Mix thoroughly for 30 seconds.  DO NOT remix or try to apply once epoxy has already started to gel.

Amber when fully cured.

Extra Strength epoxies come in both double barreled syringes and cartridges. The 0.85 oz syringe comes with a plugger and removable cap. The larger cartridges require an epoxy dispensing gun. Before opening, rest the cartridge tip up to allow trapped air to rise to the top. Gently press to expel air and ensure epoxy is dispensing evenly from both sides. When finished pull back to release pressure before capping.

Recap and place in a resealable plastic bag. Store in a cool dark place.

For all bottled kits – squeeze out all air, recap, and place in a resealable plastic bag. Store in a cool dark place.

Most bond failures are caused by not preparing all the components properly and not following mixing and curing instructions.  Below are some of the common factors that can cause bond failures.

1. Make sure all dust and any other containments are removed from all surfaces.
2. Smooth surfaces make it difficult for epoxy to grab on to. Rough up surfaces to be bonded.
3. Make sure you leave your materials to dry and cure properly at room temperature (72 F /22 C).

DO NOT handle until the epoxy has fully set or the bond will be compromised.

4. It is critical that equal amounts of Part A and Part B are dispensed. If too much Part A is dispensed it will create a weak rubbery bond and conversely too much Part B will create a brittle bond.
5. Too large of a gap between the bonding surfaces decreases the structural strength of the bond.
