Megapoxy Megadure

For equipment exposed to severe wear in mines, ball mills, coal-fired plants, dredging operations, and abrasive slurry pumps, Megadure Ceramic provides a high alumina bead epoxy lining to protect critical metal, steel, and concrete surfaces from extreme abrasion.

What it does

Megadure Ceramic is a two-component, gap-filling epoxy paste formulated with high alumina beads to resist intense abrasive wear. Applied by trowel or spatula, it fills gaps, builds a protective barrier on high-wear steel surfaces, and serves as a high-strength grout between wear-resistant high alumina ceramic tiles and pipe fittings. The system cures under ambient conditions to a distinct green colour, confirming a complete cure and indicating that the surface is ready for service.

Numbers that matter

• 0.5 m² yield per kit: A single 2 kg kit covers half a square metre at a standard 2 mm application thickness.
• 30-minute work time (Standard at 25°C): Gives installers a practical window to apply and dress the paste on larger steel or concrete surfaces.
• 10-minute work time (Quick Set at 25°C): Shorter working window for rapid repairs, achieving an initial cure in 2 hours to minimise equipment downtime.
• 10°C minimum limit: The lowest allowable application temperature to ensure the epoxy cures and develops its full physical properties.

Where to use it

This lining system is formulated for protecting industrial bulk handling and processing equipment, including:

• Lining steel surfaces, chutes, and pipe fittings
• Grouting joints between wear-resistant high alumina ceramic tiles
• Protecting slurry pumps, dredging equipment, and ball mills
• Rebuilding worn concrete and metal components in high-abrasion environments

Surface preparation

To prevent adhesive failure and ensure the lining withstands mechanical stress, prepare substrates according to these minimum specifications:

• Metals and steel: Grit blast to AS CK 9.4 Class 3 finish. If grit blasting is not possible, mechanically abrade to a clean, bright metal finish, then degrease by flooding the surface with a proprietary degreaser. Paint must be completely removed prior to grit blasting.
• Concrete: Must be completely dry, free of grease, oil, dust, and loose particles. Remove surface laitance using mechanical methods such as scabbling, grit blasting, or grinding. For painted concrete, remove all traces of paint by flame-cleaning or grinding before mechanical profiling.

Limitations

• Do not apply if the ambient or substrate temperature is below 10°C.
• Wire brushing of metal surfaces is not recommended as it provides minimal adhesion and is not satisfactory for high-wear service.
• Thorough mixing of Part A and Part B is essential; incomplete mixing will result in poor physical properties and premature failure of the lining.
