Description
Megapoxy HX Extra Low Viscosity Epoxy Resin:
• is a specially formulated extra low viscosity, 100% solids, resin based, solvent-free, hydrophilic liquid resin.
• is used regularly for the repair of cracked concrete by gravity
penetration or low pressure injection.
• is also suitable for impregnation of porous substrates such as masonry and timber.
• has also been used successfully as a low viscosity laminating resin for fibreglass work.
Features and Benefits

• Hydrophilic
• Thin Liquid
• Mixes easily by hand
• Very high strength permanent bonds
• Excellent tensile and compressive strengths, superior to concrete
• Excellent chemical resistance
Recommended Applications
• Casting
• Concrete Crack Repair
• Low Pressure Injection

• Floor Repairs
• Laminating
• Masonry Sealing
• Capillary Action
• Vacuum Bagging
How to Use
Megapoxy HX Extra Low Viscosity Epoxy Resin is a solvent-free, extra low viscosity, hydrophilic epoxy resin for many types of bonding and filling applications.
It is clear setting and it is conveniently packaged in 4 litre and 20 litre kits with a simple 3:1 mix ratio.
It has a 60-minute work time with a 24-hour cure time at 25ºC.
Surface Preparation
Before you begin mixing, you need to ensure that all contact surfaces like metal, concrete and stone are clean and clear of oil, dust and any other surface contaminants.
Concrete and stone surfaces should be prepared by grinding the surface and removing all the dust and debris. This helps ensure effective bonding contact.
Compressed air can be used to remove dust from cracks and holes. Clean metal surfaces with acetone to remove any oils or contaminants.
Safety and PPE
Megapoxy HX Extra Low Viscosity Epoxy Resin is VOC-free. As with all epoxy resins, please wear appropriate PPE, including eyewear gloves and clothing.
Mixing
IMPORTANT. Only make a suitable quantity that can be used within the 60-minute work time!
Additional batches can be mixed after the previous is mixed and applied. Even as they cure.
The recommended mixing time for Megapoxy HX Extra Low Viscosity Epoxy Resin is 3 minutes. Mix first for 2 minutes, before scraping the sides and then mix for another one minute until the product is completely uniform in colour.
Megapoxy HX is easily mixed by hand. For larger projects and larger volumes of product, you can mix mechanically.
Using measuring tubs, pour the required amount of Part A. Allow enough volume in the mixing tub for the full amount of epoxy. Pour in the correct amount of Part B.
We recommend mixing Megapoxy HX for 3 minutes using a timer. Set a timer for 2 minutes. Begin slowly mixing by placing a flat spatula into the mix (to the base of the tub) and slowly stir. The two parts are still visibly streaky until combined. As the epoxy is mixed it will change from clear to milky, then back to clear.
Ensure you scape around the base and sides to gather all the un-mixed epoxy and continue to mix.
After 2 minutes, scrape any un-mixed product off the sides of the container and the spatula before mixing again for a further one minute (set timer). After the one minute is complete the Megapoxy HX should appear even, streak-free and ready for use.
Do not be concerned if some bubbles are visible, as they will dissipate as the epoxy warms and cures. A vacuum chamber can be used to remove any bubbles for craft applications.
Application
Megapoxy HX is recommended for concrete crack injection repairs and casting.
Applying Megapoxy HX Extra Low Viscosity Epoxy Resin is easy and fast. It will cure even in cold or damp conditions. Stronger than concrete with good chemical resistance, it can be applied by paint brush directly onto cracks or poured in using a plastic dispensing bottle.
Megapoxy HX is a water and food-safe contact material for commercial surfaces (complies with AS/NZ 4020:2018 testing of products for use in contact with drinking water).
Clean Up
Uncured Megapoxy HX Extra Low Viscosity Epoxy Resin can be cleaned with Megapoxy Thinners.
Please Dispose of contents and container in accordance with local, regional, national and international regulations.
Finishing
Although applying Megapoxy HX Extra Low Viscosity Epoxy Resin is easy and fast, it will cure stronger than concrete with good chemical resistance and can be machined, sanded and polished to a fine finish.
