Grey (N35) and White
Megapoxy H Low Viscosity Hydrophilic Epoxy Resin is a low viscosity, 100% solids,
resin based, solvent-free, hydrophilic liquid resin. It is suitable for use in repairs of structures that are in contact with potable
water.
Megapoxy H Low Viscosity Hydrophilic Epoxy Resin complies with AS/NZS 4020:2018
“Testing of Products For Use In Contact with Drinking Water”. Megapoxy H is
resistant to hydrogen sulphide that may be present in pipes and plants used for
treatment of sewage.
Megapoxy H Low Viscosity Hydrophilic Epoxy Resin has excellent static and dynamic
mechanical properties, and can be used with the fine aggregates to make high
strength epoxy mortar.
It can be used for wet to dry concrete adhesive. Repairs of cracked concrete,
underwater and splashzone repairs. Megapoxy H Low Viscosity Hydrophilic Epoxy Resin is volatile organic compounds free (Nil V.O.C.)

How to Use
- Megapoxy H is a low-viscosity, hydrophilic epoxy resin for many types
of bonding, filling and coating applications. - Available in clear or N35 grey, and is conveniently packaged in 4 litre
and 20 litre kits with a simple 3:1 mix ratio. - It has a 30 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 H Low Viscosity Hydrophilic 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 30
minute work time!
- Additional batches can be mixed after the previous is mixed and
applied, even as it cures. - The recommended mixing time for Megapoxy H Low Viscosity Hydrophilic
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 H Low Viscosity Hydrophilic Epoxy Resin 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 H Low Viscosity Hydrophilic Epoxy Resin
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 H 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.
Mixing Epoxy Mortars
- Once the Megapoxy H Low Viscosity Hydrophilic Epoxy Resin has been
fully mixed, it can also have fine aggregates added to create epoxy mortars. - A recommended ratio to use is 3:1:12
-
3 ea. Part A: 1 ea. part B: 12 ea. parts Dry sands / Aggregates
- Be sure to use the same container for each part. It doesn’t matter
whether you use a 1 litre container or a 5 litre container, depending on the size
of your project. - Continue mixing sands / aggregates for another minute before
application.
Application
- Megapoxy H Low Viscosity Hydrophilic Epoxy Resin is recommended for
filling and repairs for new-to-old concrete bonding; concrete crack repair; steel
anchoring; and underwater or splash zone structures. - It is ideal for non-slip floors and as an epoxy mortar for bridge and
rail load-bearing pads, as well as industrial machinery grouting. - Megapoxy H 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 H Low Viscosity Hydrophilic 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 H Low Viscosity Hydrophilic 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. - For further technical information, refer to TDS.
