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

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

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 to a standard Sa 2.5 – Sa3 , SIS 05 5900 , ISO 8501-1.
