Use Megapoxy HX for: Concrete crack repair, masonry sealing, fibreglass lamination, and any application requiring a low viscosity, high-strength epoxy resin.
Megapoxy HX is a specially formulated, extra low viscosity, 100% solids epoxy resin designed for demanding applications. Its hydrophilic nature and exceptional penetration capabilities make it ideal for repairing cracked concrete and sealing porous substrates like masonry and timber. With superior compressive and tensile strengths, Megapoxy HX provides durable, long-lasting repairs and reinforcements. This solvent-free resin is also perfect for fibreglass lamination, offering excellent adhesion and strength. Ideal for Australian civil construction, marine trades, and building maintenance.
Primer Information: Surface preparation is key. For concrete, ensure it is clean and free from laitance. For metals, grit blasting is recommended. Priming is generally not needed due to the products excellent adhesion, however on very porous surfaces, or very demanding applications priming could be considered. Always test a small area first.
Cure Time: Cure times vary with temperature: 48 hours at 15°C, 24 hours at 25°C, and 12 hours at 35°C. Thin film cures in 4-6 hours at 25°C. This allows for flexible project scheduling based on environmental conditions.
Coverage Rate: Coverage depends on the application. For crack injection, calculate based on crack volume. For lamination, refer to fibreglass application guidelines. Due to the low viscosity, this product can penetrate deeply, reducing the amount of product needed.
Application Temperature Range: Apply at a minimum temperature of 10°C. This ensures proper curing and adhesion in a variety of Australian climates.
Chemical Properties: Megapoxy HX is VOC-free and exhibits excellent chemical resistance, making it suitable for demanding industrial and marine environments. Its hydrophilic properties also allow for application in damp conditions.

Frequently Asked Questions About Megapoxy HX
Q: Can Megapoxy HX be used in damp conditions?
A: Yes, Megapoxy HX is hydrophilic, meaning it can be applied in damp conditions. However, standing water should be removed for best results. This makes it ideal for repairs in environments with high moisture levels, common in many Australian regions.
Q: How do I ensure proper mixing of Megapoxy HX?
A: Megapoxy HX requires a 3:1 mixing ratio by volume. Use accurate measuring cups and thoroughly mix Part A and Part B until a uniform consistency is achieved. Improper mixing can lead to inadequate curing and reduced strength.
Q: What surface preparation is required for concrete repair?
A: Concrete surfaces should be clean and free from grease, oil, and laitance. Mechanical abrasion, such as grinding or grit blasting, is recommended. Acid etching can be used if mechanical abrasion is not possible. Ensure the concrete is surface dry for maximum adhesion.
Q: Can Megapoxy HX be used for fibreglass lamination?
A: Yes, Megapoxy HX is suitable for fibreglass lamination due to its low viscosity and excellent adhesion. It provides a strong, durable bond and is ideal for marine and industrial applications. Ensure proper surface preparation and follow fibreglass application guidelines.
Q: What is the working time for Megapoxy HX at 25°C?
A: The working time is approximately 60 minutes at 25°C. This allows ample time for application, especially in complex or large-scale projects. Plan your application accordingly to avoid premature curing.
Q: How do I clean tools after using Megapoxy HX?
A: Use Megapoxy Thinners to clean mixing implements and working tools. Clean tools immediately after use, before the resin cures. Wear disposable rubber gloves and follow proper industrial hygiene practices.
