Megapoxy 84 is a heat-resistant epoxy paste adhesive for installing high-alumina ceramic wear tiles onto steel or concrete and securing eccentric bushings in crushing equipment. It is designed for industrial parts exposed to abrasive service and temperatures up to 120°C.
High-temperature ceramic wear linings
Use it to bond ceramic tile linings inside chutes and processing equipment or lock inner and outer eccentric bushings in Symons cone crushers and similar machinery. Its paste consistency helps create a continuous adhesive bed beneath each tile.
Bond the liner, or protect the exposed surface?
Choose 84 to fix ceramic wear tiles or secure crusher bushings. Megapoxy Megadure is a trowelable, ceramic-bead-filled wear compound for rebuilding and shielding surfaces directly exposed to abrasive material flow; it is not a substitute for a ceramic-tile bonding bed.
Before you apply
Prepare bare steel or concrete, then combine four volumes of Part A with one volume of Part B. Trowel at approximately 1.25 L/m², press each tile firmly into the bed, and avoid high-temperature service during cure. At 25°C, the paste sets in about four hours, develops toughness over 48 hours, and reaches the 120°C service condition after 72 hours.
Can Megapoxy 84 bond ceramic wear tiles to steel?
Yes. It is designed for high-alumina ceramic wear tiles on prepared steel or concrete.
When can an 84 installation operate at 120°C?
At 25°C, allow 72 hours of curing before continuous 120°C service. The adhesive sets earlier but develops toughness over time.
Should I choose 84 or Megadure for wear protection?
Choose 84 to bond ceramic tile linings. Megadure is a ceramic-bead-filled compound applied as a protective wear lining or repair paste.
Bonds high-alumina ceramic wear tiles to prepared steel and concrete.
Suitable for locking eccentric bushings in cone crushers.
Up to 120°C continuous service after a 72-hour cure at 25°C.
4:1 mix by volume; approximately 30-minute working time at 25°C.
Prepare the steel or concrete to a clean, sound bonding surface. Mix four volumes of Part A with one volume of Part B until uniform. Spread at approximately 1.25 L/m² with a notched trowel; press ceramic wear tiles down for full, even contact. Allow 72 hours at 25°C before putting the installation into 120°C service.
Do not expose the new bond to elevated service temperatures during its first 72 hours at 25°C.
Do not apply below 10°C or over paint, rust, oil or weak surface layers.
120°C is the maximum continuous service temperature, not an immediate post-application rating.
