FIRETEX FX2003 is a single pack thin film intumescent coating.
FIRETEX FX2003 is designed for in-shop application by airless spray, to provide fire resistance for up to 120 minutes on structural steel.
After appropriate drying, FIRETEX FX2003 specifications can be exposed to the weather for up to 6 months provided that the specific use or storage does not lead to ponding water due to rainfall, condensation or other site/transportation/storage circumstances.
Recommended Application Methods
Recommended Cleanser/Thinner: Recommended Cleanser/Thinner:No 2 No 2
FIRETEX FX2003 can resist normal weather conditions for up to 6 months without topcoat provided it has had appropriate drying prior to exposure. Once an approved topcoat has been applied as appropriate to the prevailing conditions, then durability will be substantially enhanced.
If the specific use or storage could lead to prolonged contact with water due to rainfall, condensation, or other site/transportation/storage circumstances, then a recommended topcoat must be used to prevent damage to the basecoat.
For in-shop application, use FIRETEX C69 Fast-Track Blast Primer
Several primers have been approved for use under FIRETEX FX2003.
A single component material
Pack Size: 200 litre and 20 litre units
Weight: 1.32 kg/litre
Shelf Life: 2 years from date of manufacture or
'Use By' date where specified.
FIRETEX FX2003 is designed for use over a suitably prepared and primed substrate.
Ensure surfaces to be coated are clean, dry and free from all surface contamination.
Under certain circumstances it may be possible to apply FIRETEX FX2003 directly to steel blast cleaned to a minimum standard of Sa2½ BS EN ISO 8501-1:2007, surface profile in the range 50-100 microns. Consult Sherwin-Williams Technical Sales Department for further details.
Nozzle Size: 21 – 27 thou ( 0.53 – 0.69mm ) depending on application requirements
Fan Angle: 30°
Operating Pressure: 210kg/cm² (3000 psi)
The details of airless spray tip orifice size, fan angle and pressure are given as a guide. Smaller fan angles should be used where the size of the work to be sprayed makes this appropriate.
It may be found that slight variation in tip orifice size or pressure will provide optimum atomisation in some circumstances. In general, the operating pressure should be the lowest possible consistent with satisfactory atomisation.
Recommended Equipment : Use a 56:1 or 68:1 Graco King or equivalent. Use 3/8” (9.53mm) ID fluid lines where lengths in excess of 3 metres are required. In-line gun or pump filters should not normally be used. Maximum length of fluid line should not exceed 60 metres.
For use on narrow web sections, the smallest tip recommended is a 21 thou (0.53mm ) with a 60 mesh pump filter.
Application Conditions and Overcoating
This material should preferably be applied at temperatures in excess of 5ºC. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature should be at least 3ºC above the dew point and always above 0°C.
The material must be protected from moisture during the drying period. Moisture ingress prior to drying may affect the integrity and fire protective properties of the coating.
No more than 2 coats by airless spray should be applied within any 24 hour period.
If the maximum recommended thickness per coat is exceeded or high film thicknesses are overcoated prematurely, cracking may occur.
FIRETEX FX2003 is capable of withstanding external
exposure without topcoat providing:
• The product is allowed to dry for at least 24 hours at 15°C in dry conditions with good air movement and ventilation. These conditions are based on a total dry film thickness of up to 800 microns. The drying time required will be increased if the film thickness is greater than 800 microns.
• The substrate temperature is at least 3°C above the dew point at the time of application and during the drying period.
Small areas of mechanical damage can be repaired using FIRETEX M72, FX1003 or FX2003 as preferred.
Larger areas of mechanical damage should be repaired using FIRETEX FX1003 or FX2003 as preferred, applied by brush or spray.
All repairs should then have the original topcoat reinstated by brush or spray as required.
