Application equipment
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 0.457 to 0.660 mm
orifice.
2-Conventional spray:industrial equipment with suitable aircap having
a fluid tip with A 1.8-2 mm orifice .
3 -Mixer: mixer must be powered by an air motor or an explosion
proof electric motor.
4-Brush or roller.
Caution
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 confined
spaces or when the air is stagnant.
4-Always take precautions against the risks of fire
and explosions.
5-Harmful or fatal if swallowed,immediately seek medical
assistance.
6-Use fresh air masks and explosion proof equipment.
Application procedures
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 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 condition
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 %.
Surface preparation
Sand blasting or wire brushing to a standard of St2 or
Sa 2 – Sa2.5 , SIS 05 5900 , ISO 8501-1.
