Introduction
It is made of high alumina ceramic fiber, and supplemented by various binders.impurities and slags are removal through kneading and stirring. It is used for repairing of lining parts such as launder, filter box, distribution plate, thimbles.

Advantage
- Good plasticity, easy operation, good adhesion.
- Erosion resistance, non-stick aluminum, no slag, no pollution to molten aluminium
- No chemical reaction with molten aluminium no slag.
- Good thermal insulation, low shrinkage and high surface strength.
Usage
Dip the mud knife into water firs to prevent sticking.apply the refractory mortar evenly to the gap and smooth the surface. If the thickness is 10mm, dry it for 30 minutes to 1 hour. If the thickness is more than 30mm, dry it for more than 3 hours.
