Typical uses

As a high performance coating on steel and concrete

Structure in severe environments, including interior of

potable water tanks and oil tanks floors,

and other areas subject to marine weathering

and high humidity exposure .

Application information

This RANA CHEM’s product is a solvent free  glassflake epoxy

for industrial and marine use.

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 0.4 to 0.9 mm

orifice.

2-Hot airless spray .

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.

6-Harmful or fatal if swallowed, immediately seek medical 

assistance.

7-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 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 40 minute at 25°c.

4-Stir during application to maintain uniformity of material

and apply a wet coat in even parallel passes and cross coat.

5-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. Sand blasting to standard  Sa 2.5 – Sa3 ,

SIS 05 5900 , ISO 8501-1.
