Megapoxy CT5 is a specialized liquid epoxy sealant designed for the rapid encapsulation of vehicle detection loops and airport infrastructure in civil engineering environments. It provides a fail-safe 1:1 mix ratio and exceptional 40% elongation, ensuring the bond remains intact under heavy vehicle vibration and pavement movement.
This Australian-made formulation is engineered to cure under adverse damp and cold conditions, delivering a 22 MPa compressive strength and allowing road reopening within 60 minutes of application. Due to the extremely short 8-minute pot life and the inclusion of Cresylic acid, precise volume measurement and professional PPE are mandatory to prevent flash setting or chemical exposure.
Frequently Asked Questions About Megapoxy CT5
Q: How long does Megapoxy CT5 take to cure completely?
A: Megapoxy CT5 has a film cure time of 6 hours at 25°C. However, it's important to note that cure times can be affected by ambient temperature and application thickness. Always refer to the product data sheet for specific guidelines.
Q: Can Megapoxy CT5 be used in cold weather conditions?
A: Megapoxy CT5 is designed for use in various conditions, but cold temperatures can significantly slow down the cure rate. It's essential to follow the manufacturer's recommendations for cold-weather application, which may include pre-warming the product or using heating techniques.
Q: What is the correct mixing ratio for Megapoxy CT5?
A: The correct mixing ratio for Megapoxy CT5 is 1:1 by volume. It is crucial to measure equal volumes of Part A and Part B and mix them thoroughly for at least 3 minutes to ensure proper curing and performance of the product.
Q: Can sand be added to Megapoxy CT5, and if so, how much?
A: Yes, sand can be added to Megapoxy CT5 to make it less flowable for high-build applications. If sand is used, add it gradually while mixing until a uniform and homogenous consistency is achieved. Note that adding 1 litre of resin and 1 litre of sand will not result in 2 litres of volume due to air voids in the sand.
Q: What safety precautions should be taken when using Megapoxy CT5?
A: Before handling Megapoxy CT5, users should familiarize themselves with the health and safety information provided in Bulletin No. 100 and the Material Safety Data Sheet (MSDS) for Megapoxy CT5. These documents contain important safety instructions and precautions.
Q: How should Megapoxy CT5 be stored?
A: Megapoxy CT5 should be stored in a cool, dry place. Unopened kits have a shelf life of 2 years when stored correctly. Avoid exposure to extreme temperatures and moisture to maintain product quality and performance.
Use Megapoxy CT5 for:
- Encapsulating Inductive Loops: Providing durable and reliable encapsulation for inductive detector loops in roadways, ensuring accurate traffic data collection for traffic management systems.
- Encapsulating Weigh-in-Motion Sensors: Offering robust protection for weigh-in-motion sensors, facilitating accurate vehicle weight measurement for road safety and traffic monitoring.
- Encapsulating Aircraft Landing Lights: Securing and protecting aircraft landing lights on airport runways, ensuring safe and reliable operation of critical airfield lighting systems.
Why Use Megapoxy CT5 for:
- Rapid Installation: The rapid setting properties of Megapoxy CT5 minimize road and lane closures, allowing for quicker installation and reduced downtime, which is crucial for busy infrastructure.
- Durability and Longevity: Megapoxy CT5 provides a non-brittle, durable encapsulation, ensuring long-term reliability and reducing the need for frequent maintenance or repairs, leading to cost savings.
- Ease of Use: The simple 1:1 mix ratio by volume makes Megapoxy CT5 easy to mix and apply, streamlining the installation process and reducing the potential for errors.
How to apply Megapoxy CT5:
- Measure and Mix: Measure out 1 volume of Part A and 1 volume of Part B of Megapoxy CT5. Place them into a clean mixing vessel and stir thoroughly for at least 3 minutes until a uniform consistency is achieved. Ensure all sides and the bottom of the mixing vessel are scraped to avoid unmixed material.
- Mechanical Mixing (Optional): While manual mixing is sufficient, a mechanical mixer can be used. However, it's crucial to minimize splashing and air entrapment during the mixing process to maintain the product's integrity.
- Adding Sand (If Required): If sand is needed to make the mixture less flowable, add fine and dry epoxy-quality sand gradually while mixing. Continue mixing until the mixture is uniform and homogenous. Remember that the volume will not double due to air voids in the sand.
- Application: Apply the mixed Megapoxy CT5 according to the specific requirements of the application, such as encapsulating inductive loops or airport lighting. Ensure proper placement and coverage to achieve the desired results.
Megapoxy CT5 limitations:
- Specific Application: Megapoxy CT5 is specifically designed for encapsulating inductive detector loops, weigh-in-motion sensors, and aircraft landing lights. It may not be suitable for other applications requiring high flexibility or general adhesive use. Consider other epoxy products for these applications.
- Mixing Accuracy: Inaccurate mixing ratios and poor mixing will result in lower physical properties of the cured system. If the error is significant, the system may not cure satisfactorily and may discolour over time. Ensure precise measurements and thorough mixing.
Safety precautions when using Megapoxy CT5:
- Personal Protective Equipment: Wear appropriate personal protective equipment (PPE) as recommended in the Material Safety Data Sheet (MSDS), including gloves, eye protection, and respiratory protection if necessary.
- Ventilation: Use in a well-ventilated area to avoid inhalation of vapors. If working indoors, ensure adequate ventilation or use respiratory protection.
- Handling: Avoid skin and eye contact. Wash hands thoroughly after handling. In case of contact, follow the first aid measures provided in the MSDS.
- First Aid: Refer to the MSDS for detailed first aid instructions. In case of ingestion, do not induce vomiting and seek medical attention immediately. For eye or skin contact, flush with plenty of water and seek medical advice if irritation persists.
Megapoxy CT5 can be used on the following substrates:
- Asphalt: Specifically designed for encapsulating sensors and lighting in asphalt roadways, providing a durable and long-lasting installation.
- Concrete: Compatible with concrete surfaces, ensuring a secure and reliable encapsulation of equipment in concrete structures.
