ZIRCON PAINT COATINGS
Zircon has a good resistance to the alkalis in molten glass and in metal slags. It is particularly effective in contact with aluminium alloys and can be applied to refractory bricks and alumina-silicate monolithic linings with equally good results. In the aluminium foundry industry due to the non-wetting properties, layers of slag are easily removed between heats. There is also some evidence that zircon helps with corundum build up. Can be used to seal ceramic fibre blanket, boards, modules and other fibre products. Supplied ready mixed or in powder form with organic bond for mixing with water. It can be brush coated or sprayed directly on to warm refractories. Maximum service temperature 1750°C /3180°F.
Examples of Applications: Foundry Industry – for application on ladles, furnaces and launders handling molten alloys. Glass Industry – coating for glass contact applications. Power stations – on boiler hearths. Incinerators – furnace linings and after burners Ceramic Industry – to seal and protect ceramic fibre linings
