Typical uses

RANA CHEM zinc rich epoxy primer is polyamide cured

that used on abrasive blast, cleaned steel.

Other uses are:

Decks, hulls ,barges and workboats, machinery ,pipes

and tank exteriors ,oil refineries, power plants, chemical

process and waste treatment plants.

Application information

This RANA CHEM’s product is three component polyamide

cured zinc rich epoxy primer.

To obtain the maximum performance for which RANA CHEM’s

is formulated,strict 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:

1-Airless spray:standard airless spray equipment having

a 28:1 or higher pump ratio and a  fluid tip with a 0.330 to 0.660 mm

orifice.

2-Conventional spray: industrial equipment with pressure feed tank

  with suitable aircap having  a fluid tip with a 2 – 2.2 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

 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 zinc dust to resin little by little and continue stirring for

       5 minutes .

4-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 .

5- Thinning  WITH RANA THINN 80 for necessary

6-Stir during application to maintain uniformity of material

and apply a wet coat in even parallel passes after 20 minutes.

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