Super Duty. Morgan Thermal Ceramics refractory mortars are normally supplied as ready-to-use wet blends of finely-ground aggregates and special binders. They develop good strength on air drying, forming strong joints and conferring an almost monolithic structure to the brickwork. This is a highly refractory mortar, dark grey in colour, which has a high water retention characteristic. It was specially developed for laying insulating firebricks but is also suitable for use with super duty and high alumina dense refractory bricks, at operating temperatures up to 1650°C. It is supplied in a consistency uitable for shallow patching or trowelling but requires the addition of approximately 5% water for dipping. Blakite is a good choice as a single, general purpose mortar on projects involving mainly insulating firebricks but also including some dense firebricks Applications: - For laying insulating firebricks, super-duty and high alumina dense refractory bricks
- Provide resistance to infiltration of air or hot gases
- Hobby and laboratory kilns
- Retard penetration of slag and molten metal into the joints
