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 0.381 to 0.457 mm

orifice.

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.

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

in confined spaces or when the air is stagnant.

 

4-Always take precautions against the risks of fire

and explosions.

6-Harmful or fatal if swallowed, immediately seek medical

assistance.

7-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 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 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

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.
