Typical uses

This RANA CHEM’s product is recommended for long time

corrosion protection of structural steel and concrete

in severe corrosive and immersed environments.

typical areas are steel buried in aggressive soil, pipelines

of steel and concrete, tanks containing fuel or lubrication

oil, drill water, drill mud, warm water or steel and concrete

in sewage treatment plants.

Application information

This product is a polyamide cured, coaltar epoxy

coating for non-immersion as well as immersion service

excellent corrosion and chemical resistance

and full film thickness in only one coat.

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 0.457 to 0.914 mm

orifice.

2-Conventional spray:industrial equipment such with suitable

aircap having a fluid tip with a 1.8-2 mm orifice.

3-Mixer: use power mixer powered by an air motor or an

explosion proof electric motor.

4-Brush.

 

Caution

1-Handle with care.

2-Before and during use ,observe all safety labels on

packaging and paint containers.

3-Harmful or fatal if swallowed ,immediately seek medical

assistance.

4-Always take precautions against the fire and explosions.

5-Use with adequate ventilation.

6-Don’t empty into drains.

7-Take precautionary measures against static discharge.

    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 THINN80 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 ,

millscale and any other foreign material should be

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