Warning: a new type of high-temp sealant from a vendor in Houston completely failed after a single pressure cycle

It was rated for 1500 degrees, but it cracked and flaked off a flange on a boiler we were commissioning. Has anyone found a reliable brand for these extreme applications?

Right? It's a real skill to get it right.
