Another new product in 2020. Cera Glue AA is a fiber-free, ready-to-use, water-based, high-temperature-use (up to nearly 1500 C [2732 F]) bonding glue for Alumina-to-Alumina or for bonding high-Alumina content ceramics to one another. Cera Glue bonds parts together dramatically, creating a strong adhesive connection of the pieces. Apply two coats to both faces to be bonded, drying between each coating at room temperature or at 60 C, followed by heating up to at least 1500 C in any atmosphere for around ½-2 hours.
