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 0.33 to 0.38 mm
2-Conventional spray:industrial equipment
with suitable aircap having a fluid tip with A 1.4-1.6mm 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 applying paint
in confined spaces or when the air is stagnant.
4-Always take precautions against the risks of fire
5-Harmful or fatal if swallowed, immediately seek medical
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 minuts.
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 50 as needed for workability .
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.
