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.
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.
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.
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.
Megapoxy 36 DuoMix achieves minimum cure for traffic in 1 hour at 25°C, or 2 hours at 15°C. This rapid setting formulation minimises site downtime and allows for a faster return to service.
It is designed for bonding ceramic, plastic, and LED reflective road markers. It also bonds concrete road markers, concrete carpark stops, parking sensors, and delineator signage.
This epoxy adhesive bonds to bituminous and concrete surfaces. It also bonds to metal surfaces when prepared correctly, such as grit blasting to AS CK 9.4 - 1964 Class 3 finish.
No, it is recommended to remove all coatings prior to bonding. Bonding to coated surfaces will result in inferior bond strengths compared to bonding directly to a properly prepared substrate.
| Application | Key benefit | Primary trades |
|---|---|---|
| Reflective Road Markers | Achieves 7.5 MPa bond strength and minimum cure in 1 hour at 25°C, enabling rapid return to service and reducing traffic disruption. | Road maintenance, civil contractors |
| Ceramic Road Markers | Provides a strong, durable bond (7.5 MPa) to concrete and bitumen, ensuring markers remain securely fixed under traffic load. | Road maintenance, civil contractors |
| Parking Sensors | Securely bonds sensors to concrete surfaces with excellent chemical resistance, preventing dislodgement in carparks. | Carpark operators, electrical contractors |
| Concrete Carpark Stops | Offers high bond strength (concrete bond >3 MPa) and impact resistance (>12 Joule), maintaining barrier integrity in high-traffic areas. | Carpark line markers, facilities management |
| Delineator Signage | Provides reliable adhesion for base-mounted signage, resisting flex and shear forces (Slant Shear Load 135 kN after 24 hours). | Traffic management, sign installers |
Warning: This material is hazardous according to Safe Work Australia GHS 7 criteria. It causes skin irritation, serious eye irritation, and may cause an allergic skin reaction. Part B is harmful if swallowed. Both parts are toxic to aquatic life with long-lasting effects.
Wear safety shoes, gloves (nitrile rubber recommended), safety glasses, and suitable respiratory protection. Wash hands thoroughly after handling and before eating, drinking, or smoking. Contaminated work clothing should not leave the workplace.
Natural ventilation should be adequate under normal use conditions. Avoid breathing dust, fume, gas, mist, vapours, or spray.
Store in a cool, dry, well-ventilated place, out of direct sunlight, away from foodstuffs, oxidising agents, heat, and ignition sources. Keep containers upright and closed. Check regularly for spills. This product is a Schedule 5 Poison (Caution) and must be stored, maintained, and used according to relevant regulations. Part A is classified as Class 9 Dangerous Goods for transport and storage.
For disposal, ensure appropriate personal protective equipment is used. Recycle material and container if possible. Otherwise, dispose of in accordance with local, regional, national, and international regulations.
Proper surface preparation is critical for achieving the documented bond strengths and ensuring long-term performance.
Surface prep: Ensure concrete is free from grease and oil, cleaning with an industrial heavy-duty degreaser if necessary. Remove surface laitance by mechanical abrasion such as scabbling, grit blasting, or grinding. For painted concrete, flame-clean or scutch to remove all traces of paint, then complete preparation by diamond grinding or scabbling.
Primer: Not required for prepared concrete.
Surface prep: Degrease and/or solvent wash to remove road grime, oils, and grease. Mechanically roughening the surface will aid in better adhesion.
Primer: Not required for prepared bitumen.
Surface prep: Grit blast metals to AS CK 9.4 - 1964 Class 3 finish. If grit blasting is not possible, mechanically abrade to a clean, bright metal surface. After abrasion, degrease the surface by flooding with an industrial-grade degreaser. Wire brushing alone provides minimal adhesion and is not satisfactory.
Primer: Not required for prepared metal surfaces.
