Recommended Topcoats

Macropoxy P300 is only recommended to be overcoated for touch up purposes.
Prior to overcoating, these areas must be thoroughly abraded, then solvent washed using Cleanser Thinners No. 13. Allow all solvent washings to dry, and thoroughly ventilate the area before applying touch up coat. 

Surface Preparation

For tank internals and for maintenance of existing tanks, blast clean to Sa21⁄2 BS EN ISO 8501-1:2007 using angular grit. Minimum surface profile 75 microns.
Ensure surfaces to be coated are clean, dry and free from all surface contamination. 

Application Conditions & Overcoating

Macropoxy P300 should preferably be applied at tempera- tures in excess of 10°C. Relative humidity should not exceed 85% and in these conditions good ventilation is essential. The use of dehumidifiers to maintain stable environmental condition is recommended during application and curing

of the coating. Substrate temperature shall be at least 3°C above the dew point and always above 0°C.

At application temperatures below 10°C, drying and curing times will be significantly extended.

Return to Service : Applied coating must be allowed to cure for 16 hours at 3°C or above before returning to service. Should ambient temperature fall below 3°C in this 16 hour period, a further 16 hours should be allowed, once the ambient temperature rises above 3°C.

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