When industrial operations require high-alumina ceramic tiles to protect steel or concrete from extreme wear and continuous temperatures up to 120°C, a standard adhesive won't last. Megapoxy 84 provides the specialised epoxy paste solution. It ensures those critical wear linings remain securely bonded, even under sustained heat, extending equipment lifespan and maintaining operational efficiency.

Why this product exists

Megapoxy 84 is specifically formulated as a two-component epoxy paste adhesive for environments where high-alumina ceramic tile linings are essential. Its existence is driven by the need for a robust, high-temperature bond for these wear-resistant tiles onto steel or concrete substrates. This includes critical applications like locking eccentric bushings in crushing machinery, where conventional adhesives would fail under thermal and mechanical stress.

The numbers that matter

Maximum Operating Temperature: 120°C continuous service. This is not an intermittent peak; this is the continuous service temperature Megapoxy 84 reliably withstands. It ensures tile linings remain fixed in industrial applications subject to sustained heat, preventing costly delamination and premature wear in hot process environments.

Compressive Strength: 120 MPa. This significant strength ensures the bond between the high-alumina ceramic tile and its substrate can resist the intense compressive forces and abrasive wear typical in heavy industrial and mining applications.

Flexural Strength: 55 MPa. Beyond sheer compression, the 55 MPa flexural strength confirms the adhesive's ability to handle bending and shearing stresses, which is critical for tile integrity on surfaces that might experience minor deflections or vibrations during operation.

Work Time: 30 minutes at 25°C. This controlled work time provides an adequate window for mixing, applying, and accurately positioning ceramic tiles over larger areas, particularly in a hot environment, before the product begins to set.

What it's like to use

Megapoxy 84 is designed for straightforward, two-component mixing and application. For optimal performance, combine the entire contents of Part B into Part A and mix thoroughly for a minimum of 3 minutes, ensuring all material from the sides and bottom of the container is incorporated. A precise 4 parts A to 1 part B ratio ensures the final cure achieves maximum strength. Apply the mixed paste to the prepared steel or concrete surface using a notched trowel, then firmly press the high alumina ceramic tiles into the adhesive bed, ensuring full contact. Cleanup of tools is best achieved immediately using Megapoxy Thinners and warm soapy water.

Where this product excels

  • Industrial Plant Wear Lining: For bonding high-alumina ceramic tiles to steel in industrial plants where continuous operating temperatures reach up to 120°C, preventing tile delamination in high-heat environments and extending the service life of equipment.
  • Mining Operations: Securing high-alumina ceramic tiles to concrete surfaces for wear protection in mining infrastructure, forming a strong, durable bond (120 MPa compressive strength) that withstands heavy abrasion and extends the service life of high-wear surfaces.
  • Crushing Machinery Component Fixation: Locking eccentric bushings in Symons Cone Crushers and other heavy crushing machinery, providing a rigid, high-strength bond that maintains component alignment under severe operational loads and vibration.

Don't use this when

  • Not for: General-purpose structural bonding where high-temperature resistance is not a primary requirement. This product's specialisation might be overkill, and other Megapoxy products could be a better fit.
  • Not for: Applications where continuous service temperatures exceed 120°C, as the adhesive's long-term performance and integrity will be compromised.
  • Not for: Bonding materials other than high-alumina ceramic tiles to steel or concrete, as its formulation is optimised for these specific substrates and conditions.

Specialised bonding vs. general structural applications

Megapoxy 84 is a highly specialised epoxy paste, distinct from Megapoxy's general-purpose structural epoxies like Megapoxy P1 or even the high-performance Megapoxy PM. While those products offer excellent structural strength for concrete, steel, and other substrates, Megapoxy 84 is engineered specifically for one critical task: reliably bonding high-alumina ceramic tiles to steel or concrete in continuous service up to 120°C. Its formulation is optimised for this niche, where consistent performance under sustained heat and abrasive wear is paramount, distinguishing it from adhesives not designed for high-temperature tile lining applications.
