Description  
Use Megapoxy HX for: Concrete crack repair, precise casting, and laminating porous materials.

Megapoxy HX is a specially formulated, extra low viscosity epoxy resin designed for demanding applications. Its 100% solids, solvent-free formula ensures minimal shrinkage and a powerful bond, making it ideal for deep concrete crack repairs via gravity penetration or low-pressure injection. This hydrophilic resin also excels in impregnating porous substrates like masonry and timber, and serves as a reliable laminating resin for fibreglass work.

Key Features of Megapoxy HX

  • Extra Low Viscosity: Penetrates deeply into fine cracks and porous materials, ensuring thorough repairs and impregnations.
  • 100% Solids, Solvent-Free: Provides a strong, durable bond with minimal shrinkage and reduced VOCs, enhancing workplace safety.
  • Hydrophilic Properties: Bonds effectively to slightly damp concrete, expanding application possibilities and ensuring reliable repairs even in challenging conditions.
  • High Strength: Exhibits exceptional compressive, tensile, and flexural strengths, surpassing the capabilities of concrete for long-lasting repairs.
  • Versatile Application: Suitable for casting, low-pressure injection, surface hardening, floor repairs, laminating, masonry sealing, capillary action, and vacuum bagging.

Technical Overview

Megapoxy HX is engineered for superior performance in demanding applications. Its low viscosity allows for easy mixing and deep penetration, ensuring complete coverage and strong bonds. The precise 3:1 mixing ratio (Part A to Part B) is essential for optimal curing and performance.

Chemical Properties: 100% solids, solvent-free, hydrophilic epoxy resin. This formulation provides excellent adhesion and minimal shrinkage.

Application Temperature Range: Minimum application temperature of 10°C (50°F). Ensure the substrate is within this range for proper curing and bonding. Cure times vary: 60 minutes work time at 25°C, 48 hours minimum cure at 15°C, 24 hours at 25°C, and 12 hours at 35°C. Thin film cure at 25°C is 4-6 hours.

Application Information

  • Required Tools: Mixing containers, measuring jugs, low-pressure injection equipment (if applicable), spatulas, and personal protective equipment (PPE).
  • Trade-Specific Tips: Ensure accurate measurement of Part A and Part B for proper curing. For deep cracks, use low-pressure injection to ensure complete penetration. When laminating, ensure proper wetting of fibreglass materials.
  • Common Issues and Solutions: Incomplete curing can result from incorrect mixing ratios or low temperatures. Ensure accurate measurements and maintain a minimum temperature of 10°C.

Storage and Shelf Life

  • Storage Requirements: Store in a cool, dry place away from direct sunlight.
  • Shelf Life Information: Refer to the product packaging for specific shelf life information.
  • Temperature Considerations: Avoid storing in extreme temperatures, which can affect product viscosity and curing properties.

Common Questions  

Frequently Asked Questions About Megapoxy HX

Q: How do I ensure proper mixing of Megapoxy HX?

A: Measure Part A and Part B accurately using a 3:1 volume ratio. Mix thoroughly until a uniform consistency is achieved. Improper mixing can lead to incomplete curing and reduced strength.

Q: What is the ideal temperature for applying Megapoxy HX?

A: The minimum application temperature is 10°C. Warmer temperatures will accelerate curing. Ensure the substrate is also within this temperature range for optimal bonding and performance.

Q: Can Megapoxy HX be used on damp concrete?

A: Yes, Megapoxy HX is hydrophilic, allowing it to bond effectively to slightly damp concrete. However, standing water should be removed for best results.

Q: What surface preparation is required for concrete crack repair?

A: Clean the concrete surface to remove grease and oil. Remove surface laitance through mechanical abrasion or acid etching. Ensure the surface is dry for maximum adhesion.

Q: How long does Megapoxy HX take to cure?

A: Cure times vary based on temperature. At 25°C, expect a 24-hour minimum cure time. At 15°C, it's 48 hours, and at 35°C, it's 12 hours. Thin film cure at 25°C is 4-6 hours.
