SILICA REFRACTORY MORTARS / CEMENTS
SILCAS 1C
Silica based, high temperature air setting mortar with a maximum service temperature of 1550°C /2820°F Used in conjunction with high temperature insulation materials in foundries. When fired, the strength of the mortar is very closely matched to that of the insulating bricks to avoid the bricks cracking or breaking from the action of the mortar.
SILCAS HP
Silcas HP hot patch is a repair cement used to repair and seal door jambs in coke ovens. To repair foundry ladles and launders in non ferrous foundries when temp. does not exceed 1430°C / 2600°F.
SILCAS RGW
Refractory Glaze Wash for coating brick and monolithic linings best applied by brush or spray although it is sufficiently thixotropic for trowel application. The recommended method is to brush hard onto the surface to give maximum bonding and to ensure an integral coating. To achieve maximum glazing efficiency, furnace lining coated should be taken up to 1000°C if possible on the first heat. To protect from acid or chemical attack from exhaust gases. Maximum service temperature 1000°C /1830°F.
SILCAS SR
Refractory cement for in situ hot repair of the sole of coke ovens. This material is supplied dry and mixed on site and pumped into the oven. It can be spread along a sole of the oven using recoke push bar and allow to self level. Maximum service temperature 1400°C /2550°F.
