Lubisol Cover Coat

Efficient refractory products for industrial furnaces.

Cover Coat / Capping Cement
  • Lubisol Cover Coat (Capping Cement) is a dry mixture of different silicate refractory components. A liquid bond “Lubisol LFS” – Ceramic Adhesive, is supplied separately. The dry powder and the liquid bond are mixed together before the application.

    Lubisol Cover Coat is a heat setting composition and it becomes hard after being dried for 3-4 hours at a temperature above 100 °C.

    The wet mix of dry powder and liquid chemical bond starts to harden slowly at room temperature after 2-3 hours.

    The two components packed separately have a very long shelf life – more than 5 years. They can be stored in any warehouse, without any special requirements for temperature or humidity.

    The application of the Lubisol Cover Coat is done by trowel on a cold or hot surface. It can be applied as a top layer of the insulation of glass furnace crowns, or as a sealing layer on the vertical walls.
