How to Use

Megapoxy Megabond Structural Epoxy Adhesive is a two-part structural epoxy adhesive
for many types of bonding and filling applications.

It is available in pre-packaged 20 litre kits with a simple 1:1 mix ratio.

It has a 45 minute work time and a 24 hour cure time at 25ºC.

Surface Preparation

Prior to mixing, you need to ensure that all contact surfaces such as 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 Megabond Structural Epoxy Adhesive is VOC-free.

As with all epoxy resins, please wear appropriate PPE, including eyewear gloves and clothing.

Mixing

It is essential that the correct mixing ratio be used and that the Part A and Part B are
thoroughly mixed together before use.

Inaccuracies and poor mixing will result in lower physical properties of the cured system
and, if the error is sufficiently large, the system may not cure satisfactorily and discolour
on ageing.

Preparation

Concrete
Concrete should be free from grease and oil. If necessary, clean with industrial heavy duty degreaser.
When clean, remove surface laitance. This is best done by mechanical abrasion such as scabbling, grit blasting or grinding. If this is not possible acid etching must be carried out.

Mix concentrated hydrochloric acid with equal volume of water and spread at the rate of 0.5 litre per square meter of concrete surface. Allow to react for about 10 minutes and wash the area thoroughly and scrub with a stiff bristled broom to remove loose sand. Allow to dry for 24 hours. For maximum
adhesion the concrete should be surface dry.

Metal Surfaces
Metals should be grit blasted to AS CK 9.4 – 1964 Class 3 finish. If this is not possible, mechanically
abrade the surface to a clean, bright metal surface. Once this abrasion is complete, degrease the
surface by flooding with an industrial grade degreaser. Wire brushing is not entirely satisfactory and
gives minimal adhesion only.

Coated Surfaces
It is recommend to remove all coatings prior to bonding, bonding to coated surfaces will give inferior
bond strengths compared to bonding directly to a prepared substrate.

Concrete:
The surface may be either flame-cleaned, or mechanically treated with a scutching tool, to remove all
traces of paint. Complete the preparation by diamond grinding or scabbling.

Metals:
Steps should be taken to remove all paint and/or galvanizing. Good quality paint stripper should be
used, followed by grit blasting or grinding to a bright metal finish.

Clean-up

Uncured Megapoxy Megabond Structural Epoxy Adhesive can be cleaned with Megapoxy Thinners.

Please Dispose of contents and container in accordance with local, regional, national and international regulations.

Finishing

It will cure stronger than concrete with good chemical resistance.

Once cured, Megapoxy Megabond Structural Epoxy Adhesive can be machined, sanded and polished to a fine finish.
