VITSET ready mixed high alumina refractory cements / mortars are suitable for jointing, coating, and patching in all high temperature applications from 1450°C /2640°F up to 1850°C /3360°F. They are air-setting, with outstanding bonding properties at ambient and operating temperatures. Recommended bed for jointing firebricks is 3mm.

Vitset 45

Ready for use, air setting refractory mortar in a consistency suitable for trowelling and patching. It forms a strong air-dried bond with all grades of refractory bricks. It can be supplied in a thinner consistency for dip joints, coating and spraying. Vitset 45 is specially prepared to avoid settling out in the mortar box and to give maximum water retention for application to the more porous insulating bricks, for use up to service temperatures of 1700ºC

Examples of Applications:

Used for setting alumina refractory bricks, both dense and high temperature insulation bricks in

o Foundry ladles

o Foundry furnaces

o Kilns and kiln cars - ceramics

o Rotary cement kilns

Vitset 80

Ready mixed form ready to use suitable for setting bricks and can also be supplied at a thinner consistency for dipping bricks, coating and spraying. This material forms a strong air set bond with all grades of refractory bricks whether used as a joint or a render. The material is slightly expansile at 1540ºC ensuring good tight joints with no shrinkage problems at joint lines. It also has very good resistance to slag attack and it is very stable up to 1750ºC.

Examples of Applications:

Used in steel works and foundries where high temperatures are encountered such as setting high alumina bricks for safety linings in pouring ladles and setting bricks and purging nozzles in continuous casting tundishes.

Vitset 85

Ready mixed high alumina refractory mortar with maximum service temperature of 1810ºC. Suitable for higher temperature alloys and treatment vessels.

Vitset 90

Ready mixed high alumina refractory mortar developed with high purity and high refractoriness coupled with stability at high temperatures for more specialise applications with alumino-silicate and magnesite refractories.

Examples of Applications:

Used in setting sliding gate plates, purging nozzles and setting pre-cast shapes.
