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.
This product is a polyamine adduct cured coaltar epoxy
coating for non-immersion as well as immersion service
excellent corrosion 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.
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
2-Conventional spray:industrial equipment 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.
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
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.
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
in3- 4 hours at 25 °c.
4- Thinning with RANA THINN 85 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
or at least at the end 0f each working day or shift.
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 %.
The surface must be clean and dry . All dirt , grease ,
millscale and any other foreign material should be
removed.sand blasting to standard of Sa 2.5 – Sa3 , SIS 05 5900 , ISO 8501-1.
