Application information

This RANA CHEM’s product is a polyurethane top coat

providing excellent protection for steel structures in

marine and industrial environments.

To obtain the maximum performance for which this product

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 0.33 to 0.38 mm

orifice.

2-Conventional spray:industrial equipment

with suitable aircap having  a fluid tip with A 1.4-1.6mm 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 applying paint

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.

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 minuts.

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 50 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

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.
