Drying times, curing times and pot life should be considered as a guide only.

The curing reaction of epoxies commences immediately the two components are mixed, and since the reaction is dependent on temperature, the curing time and pot life will be approximately halved by a 10°C increase in temperature and doubled by a 10°C decrease in temperature.

Suitable for application on concrete floors. Ensure that substrate is sound, clean and free from surface contaminants. Moisture content must be less than 7%. The first coat of Macropoxy M262 should be thinned up to 15% with cleanser thinner 5 to assist in sealing the substrate porosity.

Where a non-skid profile is required P515 aggregate should be stirred into the Macropoxy M262 mixed paint, immediately prior to application, at a rate of 1.0kg per 5 ltr unit. Application will then only be possible by brush or roller.

Epoxy Coatings:

Colour Stability: Variable colour stability is a feature of epoxy materials which tend to yellow and darken with age. Therefore any areas touched-up and repaired with the same colour at a later date may be obvious due to this colour change.

When epoxy materials are exposed to ultra-violet light a surface chalking effect will develop. This phenomenon results in loss of gloss and a fine powder coating at the surface which may give rise to colour variation depending on the aspect of the steelwork. This effect in no way detracts from the performance of the system.

Epoxy Coatings - Tropical Use:

Epoxy paints at the time of mixing should not exceed a temperature of 35°C. At this temperature the pot life will be approximately halved. Use of these products outside of the pot life may result in inferior adhesion properties even if the materials appear fit for application. Thinning the mixed product will not alleviate this problem.

The maximum air and substrate temperature for application is 50°C providing conditions allow satisfactory application and film formation. If the air and substrate temperatures exceed 50°C and epoxy

coatings are applied under these conditions, paint film defects such as dry spray, bubbling and pinholing etc. can occur within the coating.
Numerical values quoted for physical data may vary slightly from batch to batch.
