Product Introduction
Silica mortar is also known as joint filler. It is made of silica powder and by a ratio of SiO2 powder. The binder is normally made of clay or additive.
Features
1.High adhesive strength. 2.High refractoriness. 3.Superior installation performance.
Application
Silica mortar is mainly used for laying and repair of coke oven, hot blast stove, glass furnace and other masonry of high quality silica bricks industrial furnace.
