Fire Protection Expanding Foam
Contact us for price on application
A one component polyurethane foam which cures by reacting with the moisture in the atmosphere and will stick solidly to almost any surface which either contains water or has been sprayed/painted with water. The foam comes in a handy 750mm aerosol can and is dispensed through a nozzle.
A fire rating of 1 hour 45 minutes was achieved on gaps up to 60mm
- Only use EF-FR to fill gaps with widths between 5mm and 60mm.
- For maximum adhesion always dampen surface before applying.
- In its cured state EF-FR can be used in temperatures between minus 40 and 80 degrees C.
- Surfaces should be free from grease and oil.
- Surrounding areas should be masked and protective clothing worn.
- Shake the can well and use in inverted position.

- Ensure that surfaces are firm, clean, free of dust and loose particles. Moisten the cavity or voided area to be filled with water, in order to aid installation adhesion to the substrate
- It is important to use the foam within a temperature controlled environment. The minimum temperature to which the foam can be installed should be no less than +20°C
- Protect the surrounding area prior to application, in particular when using the foam in retrofit applications. It may also be necessary to mask and protect the surrounding area of the cavity, particularly in areas where the compartment may be decorated or furnished.
- Insert the backing mineral in the joint before filling the gap. The mineral fibre is required to achieve the fire resistance period outlined in the table in the first tab
- Shake the can for two minutes, until the foam inside becomes liquid. This is essential to ensure the performance of the product. Then attach the adapter or gun to the canister
- Fill the cavity from the base of the aperture slowly and build up the layers of the foam. Ensure that the void is filled. Take care not to over-fill the cavity.
Allow the foam to cure and cut off the expanded ‘cured’ foam using a sharp bladed instrument.
Finally, dispose of empty cans by referring to local regulations.
