FIRETEX FX5090 is a water-based TCEP free thin film intumescent coating.
FIRETEX FX5090 is designed for application by airless spray to provide fire resistance for periods of up to 120 minutes on structural steel.
For use in internal dry controlled environments without topcoat. (C1 according to BS EN ISO12944-2:2017) and external urban or uncontrolled internal environments with topcoat (C3 according to BS EN ISO12944-2:2017).
A range of primers has been fire tested and approved for use under FIRETEX FX5090. Must not be applied directly to galvanized steel and zinc-rich primers.
If it can be guaranteed that application and subsequent in-service conditions will be in a C1 environment as defined in BS EN ISO12944-2:2017, then no topcoat is required. For any other situation a topcoat must be applied, consult Sherwin-Williams for advice.

6 months from date of manufacture.
This is designated by the “Use by” date on the pail. Both transportation and long term storage of the product must be in a covered environment, out of direct sunlight and in the temperature
range 5° to 35°C.
Protect from freezing at all times.
Ensure surfaces to be coated are clean, dry and free from all surface contamination.
Nozzle Size: 19 - 21 thou depending on application
Minimum Operating Pressure: 175kg/cm² (2500 psi)
The airless spray details given above are intended as a guide only. Details such as fluid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen. However, the operating pressure should be the lowest possible consistent with satisfactory atomisation. As conditions will vary from job to job, it
is the applicator’s responsibility to ensure that the equipment in use has been set up to give the best results. If in doubt Sherwin-Williams should be consulted.
Use 3/8” ID fluid line where lengths in excess of 10 feet are required. In-line gun or pump filters should not normally be used.
The material is suitable for brush application but due to the nature of the material, a ribbed appearance will result.
Application of more than one coat may be necessary to give equivalent dry film thickness to a single applied coat.
Application Conditions and Overcoating
FIRETEX FX5090 must be applied in a dry internal environment. It must not be exposed to condensation, damp or wet conditions during or after application.
In conditions of high relative humidity, good ventilation conditions are essential. Substrate temperature shall be at least 3°C above the dew point and always above 0°C.
At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired.
A minimum ambient air temperature of 5°C is required to ensure proper film formation.
Relative humidity should not exceed 80% to ensure proper film formation.
Extended overcoating times may be required at low temperatures and/or high film thicknesses.
Occasionally impaired film formation such as cracking may occur on edges of flanges and external or internal angles of structural steel, depending on geometry, over-application and
ambient conditions. This does not detrimentally affect the fire performance properties of the product.
