Application Conditions & Overcoating

Epoxy paints should preferably be applied at temperatures in excess of 10oC. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3oC above the dew point and always above 0°C.

At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired.
Application at ambient air temperatures below 5°C is not recommended.

Due to the high solids content of this material, it is not normally possible to achieve optimum film formation at dry film thicknesses of less than 60 microns by spray application. Where film thicknesses down to 50 microns are specified, the material may be thinned up to 10% with Cleanser/Thinner No.2. Thinning should be carried out with thorough stirring immediately before use.

In order to achieve optimum water and chemical resistance, temperature needs to be maintained above 10oC during curing.

If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Technical Team.

Additional Notes

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.

Macropoxy P100 is suitable for use in service temperatures
of -75°C – +120°C, for advice on conditions outside this range please consult Sherwin-Williams.

Epoxy Coatings - Colour Stability:

Variable colour stability is a feature of epoxy materials which tend to yellow and darken with age whether used on internal or external areas. 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.
Macropoxy P100 is suitable for storage in conditions up to 40°C, but the material will need to be adequately agitated prior to use.
