The following equipment is listed as a guide and suitable
equipment from other manufactures may be used:
1-Airless spray:standard airless spray equipment having
a 28:1 or higher pump ratio and a fluid tip with a 0.330 to 0.660 mm
2-Conventional spray: industrial equipment with pressure feed tank
with suitable aircap having a fluid tip with a 2 – 2.2 mm 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
5-Harmful or fatal if swallowed,immediately seek medical
6-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 zinc dust to resin little by little and continue stirring for
5 minutes .
4-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 .
5- Thinning WITH RANA THINN 80 for necessary
6-Stir during application to maintain uniformity of material
and apply a wet coat in even parallel passes after 20 minutes.
7-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 %.
