jm 3300 mortar
Description
JM 3300 :- A very highly refractory air-setting mortar suitable for laying JM 32 insulating firebricks, and high alumina dense refractory bricks and for operating temperatures up to 1760°C.
Murugappa 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.
TYPE
Refractory air-setting mortars.
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
FEATURES
- Good workability, ideal plasticity and water retention
- Low drying and firing shrinkages
- High refractoriness
- High bonding strength
- Good resistance to chemical attack
- Stability of chemical components
CLASSIFICATION TEMPERATURE
1760°C
