This water-resistant silica-aluminium glue with fine pore structure is widely used in high-temperature applications due to its exceptional thermal stability. It is commonly employed in the manufacturing of refractory materials, such as furnace linings and kiln furniture, where it provides strong adhesion and resistance to heat and chemical corrosion. Its fine pore structure makes it ideal for use in filtration systems, particularly in environments requiring the separation of fine particles or gases at elevated temperatures. Additionally, it is utilized in the construction industry for bonding ceramic tiles and other heat-resistant materials, ensuring durability in wet or humid conditions. Its water-resistant properties also make it suitable for outdoor applications, where it can withstand exposure to moisture and weathering without losing its adhesive strength.
