Megapoxy 36 DuoMix

For securing reflective road markers, ceramic markers, LED road markers, concrete carpark stops, and parking sensors, Megapoxy 36 DuoMix provides a rapid-setting structural bond to asphalt, bitumen, and concrete. Dispensed through a 1:1 twin cartridge system with a self-mixing static nozzle, this dual-component epoxy allows high-volume placement on civil and traffic projects without manual mixing errors.

Rapid traffic reinstatement

The primary advantage of Megapoxy 36 DuoMix is its fast cure window, which minimises road closure times. The formulation achieves high early strength, curing to a traffic-ready state in 1 hour at 25°C or 30 minutes at 35°C. Once cured, the epoxy delivers high impact resistance (exceeding 12 Joules) to withstand ongoing heavy vehicle tyre impacts and a compressive strength of 60 MPa to prevent crushing under load. The chemistry is VOC-free and provides excellent chemical resistance against automotive fluids, road salts, and harsh weather conditions.

Numbers that matter

• 3-minute work time (at 25°C): A tight operational window requiring immediate placement of markers and sensors after extrusion.
• 1-hour cure time (at 25°C): Rapid strength development to get traffic lanes open quickly (cures in 2 hours at 15°C; 30 minutes at 35°C).
• 60 MPa compressive strength (ASTM D695): High compressive load-bearing capability to support concrete carpark stops and heavy vehicle traffic over road markers.
• 7.5 MPa bond strength: Excellent adhesion directly to ceramic and reflective markers, exceeding the shear forces exerted by traffic.
• >12 Joule impact strength: Structural toughness designed to absorb repetitive wheel impacts without cracking or debonding from the road surface.

Where to use it

• Road marking: Bonding reflective, ceramic, and LED road markers to bituminous and concrete roads.
• Traffic control: Securing concrete carpark stops, parking sensors, and delineator signage.
• Substrates: Bituminous surfaces, concrete, metals, and previously coated surfaces (subject to preparation).

Limitations

• Do not apply below 10°C: This is the minimum application temperature for the chemical reaction to progress successfully.
• No simple wire brushing: Wire brushing metal substrates is not satisfactory and results in minimal adhesion; grit blasting or mechanical abrasion to a bright finish is required.
• Avoid bonding directly to paint or galvanising: Bonding to coated surfaces yields inferior bond strength. All coatings must be mechanically removed, flame-cleaned, or stripped back to the bare substrate first.
• Mixing precision: Incorrect volume ratios or incomplete mixing will lower the physical properties, prevent a complete cure, and cause the material to discolour on ageing. The extruded adhesive must show a single, uniform colour through the static mixer.

Substrate preparation

Concrete: Must be free from grease and oil. Clean with an industrial heavy-duty degreaser if needed, and remove surface laitance via mechanical scabbling, grit blasting, or grinding.

Bitumen: Degrease or solvent wash to remove road grime, oils, and grease. Mechanically roughening the surface improves the mechanical key and final adhesion.

Metals: Grit blast to AS CK 9.4 - 1964 Class 3 finish. If blasting is not possible, mechanically abrade to a clean, bright metal surface, then flood-degrease with industrial-grade degreaser.

Coated surfaces: For concrete, remove paint via flame-cleaning or with a scutching tool, followed by diamond grinding or scabbling. For metals, remove paint and galvanising with a high-quality paint stripper, followed by grit blasting or grinding to a bright metal finish.

System components

Each 600ml twin-pack cartridge is supplied with one static mixing nozzle. Tools and mixing implements should be cleaned immediately after use with Megapoxy Thinners.
