1.General Description
Lubisol –AZS-Seal is a monolithic refractory composition used for lining of various parts of industrial furnaces. It is very suitable for bottom lining applied under the AZS fused-cast bottom plates of glass furnaces. AZS-Seal is also suitable for hermetic sealing of AZS fused-cast crowns and port necks. AZS-Seal is suitable for many other applications: to be used as a refractory lining around the gas and oil burners of steam boilers and power generating plans, in the chemical industry, and in all other type of industrial furnaces and kilns.
LUBISOL AZS-Seal is supplied as a dry mix packed in 25 kg paper bags and it is mixed with Lubisol LFS liquid bond packed in 13 kg plastic canisters. The dry powder and liquid bond are mixed together in a mortar mixer before the application in a ratio of 88:12 weight %. For the convenience of the users they can mix 4 bags of dry powder with 1 canister of LFS liquid bond. Some small amount of water can be added at the end of the mixing to adjust the fluidity of the mix. The mixed concrete will start slowly setting at room temperature after about 1-2 hours and will become totally set after 8-10 hours. So, the material is suitable as castable or patching material for cold and hot application.
Lubisol-AZS-Seal is a heat setting composition – a mixture of different refractory ingredients with high Al2O3 and ZrO2 content. The wet mix is converted into a hard body by the heat of the industrial furnace.
The shelf life of the material in a dry warehouse is more than 5 years.

4. Safety Data Sheet
The material LUBISOL AZS–Seal is non flammable and non explosive. It is safe for any kind of transportation. No special requirements are needed. The liquid bond Lubisol LFS contains a diluted mineral acid. Safety measures should be taken to protect the hands and eyes of the workers with protective gloves and goggles. The acid is easily soluble in water.
