For backfilling and encapsulating inductive detector loops, traffic loops, and aircraft landing lights on asphaltic and concrete roadways, Megapoxy CT5 provides a rapid-setting, pourable seal. This cold-pour liquid compound sets under adverse cold and damp conditions, allowing civil contractors and traffic technicians to minimise road and lane closures.
Megapoxy CT5 cures to a non-brittle, flexible state with high dielectric strength, protecting sensitive wiring in roadway lighting, automatic gate loops, hearing loops, and weigh-in-motion sensors. The cured compound absorbs the physical stress of constant vehicle traffic without cracking. For high-build and bulk applications, the flow of the mixed liquid can be modified by gradually blending in fine aggregate (such as blue stone) and dry epoxy-quality sand after the initial chemical mix is complete.
Measure 1 part by volume of Part A and 1 part by volume of Part B into a clean plastic bucket. Stir thoroughly for at least 3 minutes, ensuring the sides and bottom of the vessel are scraped clean of unmixed material. A mechanical mixer may be used, keeping splashing to a minimum to prevent air entrapment, until the mixture is uniform, black, and free of streaks. If sand or fine aggregate is required to reduce flow for sloped or high-build applications, mix Part A and Part B thoroughly first, then add the dry sand gradually while continuing to mix until homogenous.
Clean mixing implements and working tools immediately after use with Megapoxy Thinners. Wear disposable rubber gloves during handling and mixing to maintain proper industrial hygiene.
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.
