Monolithic Refractories

INCT Series

INCT is a castable with excellent insulating properties, which can be directly used on the surface and operating surface of various equipment to prevent heat dissipation and provide stable refractory and insulation properties at high temperatures. Its selection should be considered based on the temperature inside the furnace, insulation properties, and construction methods. Casting, troweling, and spraying are possible construction methods.
