Customer Questions

What is ideal temperature range for curing HXTAL? The higher the faster?

The best temperature and humidity range for HXTAL is between 68 and 72 degrees F and around 40 percent relative humidity.

Can hxtal be applied to a glass surface that has been mirrored? For example, to adhere a metal mount to mirrored glass.

Yes, but the weak spot of the joint will be the mirroring on the glass and not the HXTAL. The HXTAL will bond to the mirroring but the mirroring may shed from the glass over time.

how many sq. ft. will the 1 pound kit cover?

The calculations we provide are that a 6-inch x 6-inch square gluing to another 6-inch x 6-inch square will take 10-14 grams of HXTAL. The 1 lb kit has 456 grams in it, from there you can do the math to calculate for your work.

How many ounces are in the bottles, so I know whether I need to buy this or a bigger size for several simple crack repairs, some small castings for repairs, and doing some testing first with color matching and frosting/etching matching before using on the items to be repaired.

The 1/4 pound kit is 4 ounces total: 3 ounces of A and 1 ounce of B. The 1/2 pound kit is 8 ounces total: 6 ounces of A and 2 ounces of B. The 1 pound kit 16 ounces total: 12 ounces of A and 4 ounces of B.

Can I use this on the edge of functional bowls - to seal those minute holes you can get doing drop vessels. These will serve as soup bowls, I would just fill the pin holes on the edge from cutting off the rim.

HXTAL has not been tested or approved by the FDA for food safety so we can't recommend it for this type of purpose. It will seal the holes nicely, but it cannot be sold as food safe.

How long does it take to cure?

HXTAL is set in 3 days at room temperature so pieces can be moved and jigs holding pieces together can be removed. Full cure happens at 7 days at room temperature.

can hxtal be used to secure a crack in a fused glass bowl?

Yes, Hxtal will stabilize the crack and minimize its appearance.

Where can I find the HxTAL MSDS sheet?

Our SDS sheets and Instruction Sheets are all found under our Support Section. The SDS sheets are listed here.

Can Hxtal be used for casting small things? Can it react with the patina on the metal?

HXTAL can be used to cast small items, yes. You can make a mold of the missing piece and cast the HXTAL into the mold. The finished piece can then be joined to the main piece with HXTAL to complete the part. With the patina on the metal, it can possibly...

What is the shelf life of this product if tightly sealed and properly stored? Also, I leave in the desert southwest, and keep my house at 78-82 degrees during the summer, so should I store it in a refrigerator?

HXTAL Corp gives the material a one-year warranty, but we've had customers using the same batch for up to eight years without any issues. Part A of HXTAL can handle temperatures up to 100 degrees F without any issue. Still, Part B is more susceptible...

My Part A has some crystalization on the bottle; is it not good at all anymore, or is there something I can do to revive it?

Part A of HXTAL will absorb and crystallize moisture, so those crystals are just moisture that has infiltrated the mixture. You can take the cap off the Part A and warm it up to around 100 degrees F until it clears back up again.You are just evaporating...
