Zircon patch is a specially blended product consisting mainly of zircon grades with plasticizers and a chemical bond. It is supplied ready-for-use, in a putty consistency for direct application by hand or suitable implement. Zircon patch can also be supplied in powder form which can be mixed with Zircon Bonding Solution to give consistencies suitable for tamping, trowelling or pouring. Zircon Patch will give good strength on drying at ambient temperature but is best heated to 200/300°C, for optimum strength and service performance. It is a high strength patching material for hot and cold repairs in glass tank furnaces. It is suitable for repairs to Zircon, Silica, Mullite, Alumina and in fact, any non-basic refractories.
