Surface preparation

METALS

Metals should be grit blasted to clean surface. If this is not possible, mechanically abrade to clean bright metal surface and degrease by flooding the abraded surface with Megapoxy Thinners. Wire brushing is not entirely satisfactory and gives minimal adhesion only.

CONCRETE

Concrete should be free from grease and oil. If necessary, clean with industrial heavy duty degreaser. When clean, remove surface laitence. 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 metre 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 concrete should be dry.

Painted surfaces

METALS

Steps should be taken to remove all paint. : Good quality paint stripper should be used, followed by grit blasting

CONCRETE

The surface may be either flame-cleaned, or mechanically treated with a scutching tool. Complete the preparation by grinding or scabbling

Processing data

Mixing Ratio	1 part “A” to 1 part “B” by volume
Mixing	Mix until uniform grey
Usable life at 25°C	60 minutes
Minimum cure time	24 Hours at 25°C
Full cure time	4 Days at 25°C
Minimum recommended application temperature	10°C

Mixing precautions

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 aging.

Maximum operating Temperature	80°C
Density	1.45 kg per litre
Dielectric strength 50Hz @ 25°C (Kv/cm)	190

Cleaning up

To keep mixing implements and working tools clean, use Megapoxy Thinners. Use disposable rubber gloves to protect hands and maintain proper industrial hygiene. For further details refer to Safety data sheet.
