Here are some Helpful Hints for using this product.

Extend the life of your broken refractories – The power of BN is now available in a convenient patching compound

Cera Patch allows industrial users to fill in refractory defects with Boron Nitride (BN).  BN is superior to anything you may have tried before.  Cera Patch does not sinter, shrink or crack with use.  Also, because it uses BN, Cera Patch is non-wetting with molten aluminum.  Cera Patch is applicable for all environments to 800°C (1472°F) for continuous use, and to 1000°C (1832°F) for intermittent use.
