Description
Megapoxy Megabond Structural Epoxy Adhesive
– 20 Litre Kit – comprising 10 Litres Part A, 10 Litres Part B
– Creamy White Colour
Megapoxy Megabond Structural Epoxy Adhesive is a high strength two component 100%
solids epoxy adhesive which is creamy white in colour, easy to mix and spreads
easily with a notched trowel. Megapoxy Megabond Structural Epoxy Adhesive is
suitable for bonding stone and tile to all masonry surfaces including cement sheet,
cement render, plasterboard and timber, and is suitable for both interior and
exterior applications. It will not stain light coloured marbles and bonds water
sensitive and composite stone. It can be coloured to suit using Megapoxy coloured
pigment pastes and has high shock and chemical resistance.

How to Use
- Megapoxy Megabond Structural Epoxy Adhesive is a two-part structural
epoxy adhesivefor 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.
Coated 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.
Coated 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. - For further technical information, refer to TDS.
