AVERAGE DRYING TIMES

  • To touch: 3 hours (@ 15°C), 1½ hours (@ 23°C)
  • To recoat: 6 hours (@ 15°C), 4 hours (@ 23°C)
  • To handle: This will depend on the total thickness of

FIRETEX FX5090 to be applied.

No more than two coats by airless spray should be applied within any 24 hour period

These fi gures are given as a guide only. Factors such as air movement and humidity must also be considered.

RECOMMENDED PRIMERS

A range of primers have been fi re tested and approved for use under FIRETEX FX5090.

Please consult Sherwin-Williams for detailed information.

Must not be applied directly to galvanized steel and zinc rich primers.

RECOMMENDED TOPCOATS

If it can be guaranteed that application and subsequent in-service conditions will be in a C1 environment as defi ned in ISO 12944-2:1998, then no topcoat is required.

For any other situation a topcoat must be applied, consult Sherwin-Williams for advice.

PACKAGE

A single component material

  • Pack Size: 20 litre units
  • Weight: 1.40 kg/litre
  • Shelf Life: 6 months from date of manufacture or ‘Use By’ date where specifi ed. Protect from frost.

SURFACE PREPARATION

Ensure surfaces to be coated are clean, dry and free from all surface contamination.

APPLICATION EQUIPMENT

Airless Spray

Nozzle Size: 19 - 21 thou depending on application requirements

Operating Pressure: 175kg/cm² (2500 psi)

Petrol Unit:

Nozzle Size: 19 - 21 thou depending on application requirements

Operating Pressure: 175kg/cm² (2500 psi)

The airless spray details given above are intended as a guide only. Details such as fl uid 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 SherwinWilliams should be consulted.

Use 3/8” ID fl uid line where lengths in excess of 10 feet are required. In-line gun or pump fi lters should not normally be used.

Brush

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 fi lm 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 signifi cantly extended, and spraying characteristics may be impaired.

A minimum ambient air temperature of 5°C is required to ensure proper fi lm formation.

Relative humidity should not exceed 80% to ensure proper fi lm formation.

Extended overcoating times may be required at low temperatures and/or high fi lm thicknesses.

Occasionally impaired fi lm formation such as cracking may occur on edges of fl anges 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.

If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Sherwin-Williams. 

ADDITIONAL NOTES

In common with other water based coatings, the drying of this material is retarded by high humidity conditions. Lack of air movement also slows down the drying process, and under such conditions it is advisable to introduce some method of circulating air over the coated surface in order to speed up the drying. A ventilated air speed of 2 metres per second is recommended.

Numerical values quoted for physical data may vary slightly from batch to batch.

HEALTH AND SAFETY

Consult Product Health and Safety Data Sheet for information on safe storage, handling and application of this product.

Unlike many other water based intumescent coatings, FIRETEX FX5090 does not contain tris-chloro ethyl phosphate ( TCEP ).

TCEP is a category 3 carcinogen, which would cause products to be classifi ed as harmful. Since FIRETEX FX5090 is TCEP free, it is not classifi ed as harmful by the Chemicals (Hazard) Information and Packaging for Supply Regulations 2002.

WARRANTY

Any person or company using the product without fi rst making further enquiries as to the suitability of the product for the intended purpose does so at their own risk, and Sherwin-Williams can accept no liability for the performance of the product, or for any loss or damage arising out of such use.

The information detailed in this Data Sheet is liable to modifi cation from time to time in the light of experience and of normal product development, and before using, customers are advised to check with Sherwin-Williams, quoting the reference number, to ensure that they possess the latest issue.
