is formulated,strict adherence to all application,instructions,

precautions,conditions and limitations is necessary.

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- 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.

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 3-4 hours at 25 °c .

4- Thinning  with RANA THINN 84 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 to a standard of Sa 2.5 – Sa3 , SIS 05 5900 , ISO 8501-1.
