Dual Crown Overcoat Process

In the case of severe crown damage, another option is Fosbel’s innovative Dual Crown Overcoat Process, which utilizes a combination of an Overcoat plus Ceramic Welding for superior internal and external crown restabilization. This enables better sealing of the crown to:

  • Extend furnace life
  • Reduce fuel consumption
  • Protect the crown investment
