Airport lighting installations and road sensor projects demand speed. Downtime means disruption and cost. Megapoxy CT5 is the purpose-built encapsulation compound that delivers rapid return to service. It cures fast, even in cold or damp conditions. Critical roadway electronics are secured quickly, reliably, and non-brittle for the long term.
Roadway infrastructure faces unique challenges: constant traffic load, extreme weather, and the need for minimal disruption during installation. Megapoxy CT5 was engineered specifically for encapsulating sensitive in-road components like inductive detector loops, weigh-in-motion sensors, and aircraft landing lights. It prevents costly re-dos by providing a robust, long-term solution that withstands the dynamic forces of asphalt and concrete roadways, setting quickly to minimise lane closures.
Megapoxy CT5 offers a work time of just 8 minutes at 25°C, allowing crews to complete critical encapsulation tasks rapidly before the material begins to set. It achieves initial cure in 6 hours at 25°C, or 12 hours at 15°C, enabling a swift return to service for roads and runways even in cooler conditions. Its 40% elongation at break ensures a non-brittle encapsulation that can flex and move with the substrate, resisting cracking and failure under traffic loads. A Shore D hardness of 60-70 provides excellent durability without becoming overly rigid, protecting embedded electronics from impact and vibration.
Megapoxy CT5 is a simple 1:1 mix ratio by volume, making preparation straightforward. Both parts are pre-measured in kits for immediate use. Mechanical mixing is recommended for thorough blending, but care should be taken to minimise splashing and air entrapment. Precision in mixing is crucial; incorrect ratios or insufficient blending will compromise the final cured properties. For high-build or bulk applications, dry epoxy-quality sand or fine aggregate can be gradually added while mixing to adjust consistency. Cleaning of tools and mixing equipment is accomplished with Megapoxy Thinners.
This compound is specifically formulated for critical installations on asphaltic and concrete roadways:
Megapoxy CT5 is typically the final step in securing embedded electronic components within new or repaired road surfaces. After the sensors or lighting elements are positioned, CT5 is poured into the routed channels or cavities. Its rapid cure and ability to bond to both asphalt and concrete make it ideal for immediately returning traffic to the treated area. The compound protects the sensitive electronics from the harsh road environment, acting as a robust, non-brittle barrier against moisture, vibration, and physical damage from traffic.
Megapoxy CT5 is engineered as a highly specialised compound. Unlike more general-purpose epoxies or concrete coatings, CT5 is purpose-built for the specific demands of encapsulating in-road electronics and aircraft lighting. It is not formulated as a standard adhesive, a structural concrete repair material, a flexible joint sealant, or a broad-area floor coating. Its unique blend of rapid cure, non-brittle performance, and tolerance for adverse conditions makes it distinct within the Megapoxy family, ensuring optimal results where these highly specific requirements converge.
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.
