High Temperature Adhesive, 2000F Rated, Sodium Silicate, Water Glass, 40% Solution, 4oz Bottle, 5602 Clear

Had Dinos in my reef tank. This cleared them up in three weeks. Didn't even use a quarter of it.

This sodium silicate solution helped me restore a ceramic, flame guard (for a gas torch) that had broken into five, irregular pieces. I painted the solution onto the broken edges of the ceramic pieces, assembled them back into a cylindrical shape, and used a tiny rubber band to “clamp” the fragments together.In 30 minutes, the solution had set into a hard, clear, mineral “glass.” I could remove the rubber band “clamp” and the pieces of ceramic held together for handling without any additional support. I used more solution to fill some small gaps where chips of the original ceramic were missing.Per the instructions, I let the solution plus joined and patched pieces cure for 24 hours. Then, I used diamond files to remove the excess, hardened solution, and to shape the reconstructed areas. I was surprised at how hard the “cured” solution was, and how well it resisted abrasion from the diamond files.The reassembled and restored, flame guard was even stronger than before. I tapped on it with a small, brass hammer, to seat it into the torch nozzle, and it did not break apart. It has withstood the high heat from the blue flame of the gas jet without disintegrating.I am really impressed with this product. Its bonding strength and heat resistance on ceramic components is spectacular.P.S. I did not experience any fumes from this product, and it dilutes and cleans away well with water. Do be careful not to let it into your eyes or mouth, or to have prolonged skin contact, as the solution is a strong base (alkaline) that is caustic to soft tissues.UPDATE 05/08/2022:The cured sodium silicate easily sustains under heat from a blue flame, which is between 2000 - 3000 deg. F. However, unless sealed with a silicone or other, water-resistant coating or film, it will readily dissolve in water or upon contact with it.Also, the sodium silicate conducts electricity, and anything that is coated or permeated with it will not be insulated against electrical current.

This product has multiple usages from the aquarium trade to making adhesives. Using the product in a reef tank to induce a diatom bloom, in order to battle small cell amphidinium dinoflagellates. Works well to induce the bloom to out complete the dinos.

As the title says. It is what it is. I will note there was some precipitate that had settled to the bottom, which to be fair is typical of old silicate solutions.

It works just as described and is easy to apply. Used a heating gun to dry it and left it overnight, and the ceramic held well together. The joint is clean, and the “glue” is hard to detect since it is clear. Will buy it again.

We got this glue to make it easier to build double wall pipe for wood stove. Glue didn't work. And of course you can not sent open chemicals back. Would not purchase.

this product was either diluted or old enough to denature - none the less it did not perform in making slip. an entire bottle did not defloc 50 lbs of slip powder. an alternative brand, in a squat tub, performed as expected. I would not rebuy this product simply as it was worthless. a side by side comparrison proved it did not work as one would expect 40% to work.

I haven't actually fired up the heater yet but I repaired several with this liquid glass. This stuff works great if they're broken pretty clean where the pieces fit back together like they're supposed to and no gaps I would put a little on each surface stick it together then in a few minutes when it's dry enough lay it on a side and then brush on the bead over the crack then flip it over and do it on the other side. Just a small miniature brush works great like you would use for a very small painting project like a quarter inch wide brush works great.
