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 ,
