Cera Glues
Products for very special applications
Cera Glue AA
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. Also this glue can be used with dense or porous surfaces: just 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. NOTE that this product DOES NOT contain Boron Nitride.
- Specifically designed for Alumina-to-Alumina or for high-Alumina parts
- Usable to nearly 1500 C, higher than other bonding agents
- Glue is highly stable/unreactive with many materials – even molten ones
- Provides very strong joining of parts
- YAG (YAG, 3Y2O3*5Al2O3) based, phosphate-refractory bonded
- Contains no RCF (Refractory Ceramic Fiber)
- Water-based – easy cleaning and diluting if needed
- Bonding parts
- Glue-repair of broken or chipped ceramic/refractory parts
- Hermetically sealing tubes and bonded parts
- Creating large complex parts from separately sintered components

Cera Glue Sealcoat
Cera Glue – Sealcoat is a water-based coating that can glue ceramic pieces as well as forming a vitreous impervious seal on most ceramics that withstands thermal cycling. This product requires a one-time bake-on at 800-850 C for ½ to 1 hour for use up to nearly 800 C (1472 F).
- Bonds ceramics
- Vitreous layer of non-silica ‘glaze’
- Applied like house paint
- Safe, water-based
- Gluing ceramic pieces and boards
- Sealing ceramic surfaces from gaseous

Cera Glue GG
Cera Glue GG is a fiber-free, ready-to-use, water-based, bonding glue for Graphite-to-Graphite or for bonding Silicon Carbide ceramics to one another. Cera Glue GG bonds parts together dramatically, creating a strong adhesive connection of the pieces. Apply glue to both faces to be bonded and place them together while still wet; then dry the pieces thoroughly at room temperature (i.e., overnight) and/or at 60 C. To achieve the bond, Cera Glue GG requires a one-time bake-on at >= 800 C (>= 1472 F) for ½ hour.
- Specifically designed for Graphite-to-Graphite or for SiC-SiC
- Usable to nearly 1000 C in air
- Protects Graphite from oxidation
- High Emissivity
- Withstands cyclic use
- Contains no RCF (Refractory Ceramic Fiber)
- Water-based – easy cleanup
- Bonding parts that would be difficult to make as monolithic
- Glue-repair of broken or chipped Graphite or SiC parts
- Sealing surfaces, fissures, gaps

Cera Glue Bondcoat
Cera Glue BondCoat is a water-based paste that can glue/bond high-temperature ceramics, such as high-density Zirconium Dioxide and Silicon Carbide, as well as Boron Nitride. This product requires a one-time bake-on/bonding heat treatment at 1300-1500 C for 1/2 to 1 hour in an atmosphere compatible with the material being bonded (i.e., air, nitrogen, argon, etc.).
- Bonds dense refractory ceramic of ZrO2, SiC, BN
- Bonded material can be used at temperatures up to the bonding heat-treatment temperature
- The bond/glue is stable with many materials and provides very strong joining of parts
- Applies smoothly and spreads easily
- Safe, water-based
- Gluing dense refractory ceramic pieces
- Joining parts, such as 3D printed pieces, into complex structures
- Sealing ‘gaps’ and fissures
