|High Temperature Cement A14 & A28
Skyline Components, LLC
A14 and A28 high temperature adhesive can provide high bonding
performance between ceramic fiber boards, blankets and other ceramic
fiber insulations. They can be used to bond ceramic fiber insulations to
firebricks and other refractory materials. They can also be used to repair
ceramic fiber boards, firebricks in stoves, fireplaces, barbeque grills,
heaters, furnaces, wood stoves, coal stoves, and other units that have
ceramic linings. Moreover, They can be tucked in to board and firebrick
joints to form a seal, or coat on board and firebrick surfaces to seal up
cracks and fill in minor voids.
The upper service temperature can be up to 2600°F for A14 and 2800°F for
A28. They are prepared to a mortar and ready for use. They can be applied
by brushing or trowel. After drying they form a hard bond.
- High bonding strength
- Thermal shock resistance
- High temperature stability
- Good chemical stability
- Clear each surface to be bonded by removing contaminants and
dust. Surfaces with high water absorption should be wetted with
water before using the coating.
- Mix the adhesive well because material may settle while transported
- Apply the adhesive to each surface to be bonded, and contact
surfaces together with light but firm pressure. Excess adhesive can
be brushed away from the bond site.
- The adhesive is air-sitting glue. Allow it to dry at room temperature,
or an elevated temperature (don’t exceed 100°C (200°F)), for about
24-48 hours. Higher temperature will help curing. If temperature is
too low (<15°C (60°F)), more time may be required for curing.
However, the adhesive dried at room temperature is not water-proof.
Final curing should be done at high temperature (>1000 °F).
A14 and A28 high temperature adhesives must be protected from freezing.
Normal shelf life is 6 months in unopened containers that have been
