 Typical uses

As a general purpose rust preventing primer

in paint systems.

For long-life protection of steel exposed to

moderately to severely corrosive environment.

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 fine finish tip with

  a 0.4 mm to a 0.55 mm or larger.

2-Conventional spray:industrial equipment with suitable

   aircap having  a fluid tip with a 1.4-1.6 mm orifice .

3-Mixer:mixer must be powered by an air motor or an explosion

         proof electric motor.

 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 procedure

1-Flush equipment with recommended 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 .

Note:since the pot life is limited and shortened by high

temperatures ,do not mix more material than will be used

in 3 hours at 20 ^°c.

4-Stir during application to maintain uniformity of material

and apply a wet coat in even parallel passes.

5-Clean all equipment with cleaner immediately after use

or at least at the end 0f each working day or shift .

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