This RANA CHEM’s product is a polyamide epoxy intermediate
Coat in industrial and marine use.
To obtain the maximum performance for which this product
is formulated,strict adherence to all application,instructions,
precautions,conditions and limitations is necessary.
The following equipment is listed as a guide and suitable
equipment from other manufactures may be used.
adjustments of pressure and change of tip size may be
needed to obtain the proper spray characteristics.
1-Airless spray:standard airless spray equipment having
a 28:1 or higher pump ratio and a fluid tip with a 0.381 to 0.457 mm
2-Conventional spray:industrial equipment with suitable
aircap having a fluid tip with a 1.6-1.8mm orifice .
3 -Mixer:mixer must be powered by an air motor or an explosion
proof electric motor.
4-Brush or roller.
1-Handle with care.
2-Avoid inhalation of possible solvent vapours or
paint mist,as well as paint contact with skin and eyes.
3-Apply only in well ventilated areas and ensure that
adequate forced ventilation exists when paint applies is
in confined spaces or when the air is stagnant.
4-Always take precautions against the risks of fire
6-Harmful or fatal if swallowed, immediately seek medical
7-Use fresh air masks and explosion proof equipment.
1-Flush equipment with cleaner before use.
2-Stir resin to an even consistency with a power mixer.
3-Add cure to resin and continue stirring for 5 minutes.
Note:since the pot life is limited and shortened by high
temperatures ,do not mix more material than will be used
in 8 hours at 25 °c.
4- Thinning with RANA THINN 80 for necessary
5-Stir during application to maintain uniformity of material
and apply a wet coat in even parallel passes after 20 minutes.
6-Clean all equipment with cleaner immediately after use.
Environmental temperature must be 10-40°c.
Surface temperature must be at least 3°c above dew point
to prevent condensation. At freezing temperature surface
must be free of ice and relative humidity below 80 %.
The surface must be clean and dry .All dirt grease and other
foreign materials should be removed .old primed surface
must be smoothly wire brushed.
