Store in a cool dry place at a temperature between 50F-70F.  Do not use if the product has been exposed to high temperatures for an extended period of time.  The cartridge should be stored standing upright and purged immediately after removing the nose plug to eliminate any air that might be trapped in the cartridge.  Use within 24 months of date of manufacturer.  The product can be stored with the mixer tip attached as long as the outlet is clean before attaching a new mixer tip.

Only use the recommended and supplied mixer tips that have been engineered for the supplied cartridge.  Use mixer tips that are clean and free of any blockage. If the material has started to gel in-between jobs then discard and reuse a new mixer tip.

Use a recommended dispenser that is in good working order and free of broken parts.  Dispensers with a higher mechanical advantage can cause problems of off ratio mixing.  To minimize off ratio mixing use light constant pressure on the trigger and do not force the adhesives out of the cartridge.

Bring the sheet goods to a temperature of 60F-70F before fabrication.  Glue that is dispensed and used on cold sheet goods may not fully cure resulting in lower bond strength.

Glue that has been stored in a refrigerator must be brought up to room temperature before use.  The product may not mix correctly if it is too thick to pass through the mixer tip or may not achieve enough heat to trigger the chemical reaction.  To avoid damage do not heat past 100F

Use the correct trigger action to achieve on ratio mixing.  Apply and maintain constant pressure on trigger; do not stop and let adhesive run on in-between strokes.  Once you come to the end of a stroke, rapidly re-trigger the dispenser and maintain the constant pressure once again until either the job or cartridge is completed.  If the dispenser is set down for any amount of time, purge the contents of the mixing tip to ensure a correct ratio is present in the mix.

While it is always best to use the recommended glue color match, it is not always possible.  Stealth is a glue specially formulated to work on many different sheet colors.  It is recommended that you always have some on hand as it will get you by in a pinch.  Stealth blends in to match the surfacing material when a nice tight fit is achieved for seams and laminations.

Follow the instructions below to achieve a tight fit and near invisible seams:

Remove the cap and plug from the cartridge.  Purge a little to see that both the glue and hardener are flowing properly then attach the mixing tip.  Place the cartridge in the gun and purge again.  After the mixing tip is on, you should always dispose of the first 5 or 10 ml to make sure the mix is correct.

You can now fill the inlay area with glue.  The glue should overfill the groove to allow proper sanding and finishing.  They may be small air bubbles in the mix until the mixer tip is fully wetted out.  Pop any bubbles at the surface with a sharp object immediately after filling the area.  It is critical to allow the inlay to cure completely before finishing is done.  Allow extra time to ensure the cure is complete.  Remember that the glue shrinks during the cure and sanding too early may result in a recessed inlay.

When finished with the cartridge, remember to always store it upright on its base to allow any trapped air to rise toward the outlet.

There are a couple of recommendations to keep in mind when using 10 to 1 dual component glues for fabricating solid surface and stone.

One of the most common misconceptions regarding 10 to 1 glues is that all dispensers provide identical performance, Based on our experience and extensive testing, we know that there are marked differences in cure consistency.  Specifically, the lower cost all metal dispensers tend to have a very high mechanical advantage.  This high mechanical advantage can result in off ratio mixing of the two components if the user pulls too hard on the trigger.

To explain it another way, a high mechanical advantage in combination with operator strength will result in excessive pressure on the cartridge causing the cartridge to bulge slightly.  When the cartridge returns to its original size after the trigger is released, the glue component (large side) will continue to flow out of the cartridge while the activator component (small side) will not.  This problem results in an area of the bead where the 10 to 1 ratio is off and the glue bead will have "hot" and "cold" spots in the cure.

To test this theory for yourself, simply take a cartridge of glue (a lighter color will give you the best result), purge as always, and lay out a bead of 6 feet or so on wax using an excessive amount of pressure on the trigger.  Every time you re-trigger, deviate from the bead a little as a mark for later.  Continue to crank on the trigger and run out about a third of the cartridge.  Make sure to pull hard on the trigger.  This will mimic the high mechanical advantage of a lower cost gun if you are using a higher quality tool.  If you are already testing with a metal dispenser, the results will be accentuated.  

Observe carefully the differences in the curing material along the length of the bead. Notice how there will be sections of bead that cure significantly slower than other others. If you have used a light color, you may also see areas of discoloration due to "hot spots". These "hot spots" cure faster because there is the same ratio fluctuation. In extreme circumstances, the bead may not cure at all in small sections or the discoloration will ruin the appearance of the seam.

To solve cure issues, the answer lies in both the operator and dispenser.  If you want to use an economy model for cost savings, be sure to apply even pressure on the trigger to minimize ratio fluctuation.  The best option is to purchase a higher quality tool that is designed to limit the adhesive output and provide an even cure.
