Technical Data Sheet
One part high yield fire-rated polyurethane foam
Sika Boom®-FR is a one part high yield fire rated polyurethane foam.
Sika Boom-FR can be used for:
Filling gaps and voids.
Blocking out dust noise and draft.
Thermal installation of window and doorframes.
Thermal insulation of pipes.
Joint firerating can only be achieved when designed with respect to the fire report (please see report for various joint orientation)
Suitable for application at lower temperatures (+5ºC)
Excellent thermal insulation
Resistant to temperatures ranging from -40ºC to +100ºC
Approvals / Standards
Report on likely performance if tested in accordance with AS1530.4-2005 assessment based on testing to BS476 Part 20: fire rated up to 4 hours fire protection. Warrington fire test reports available on request.
Storage and Shelf Life
12 months from date of production if stored in undamaged original sealed containers in dry conditions and protected from direct sunlight at temperatures between ±18ºC and ±20ºC. The aerosol cans must be stored in a vertical position. For optimum yield opened cans should be used in 4-6 weeks.
750 ml can (12 cans per box)
Technical Data (Typical)
1 part polyurethane moisture curing
0.018 0.024 kg/l (=18-24kg/m3)
8 ± 2 minutes (23ºC/50% r.h.)
A 20 mm bead of expanding foam can be cut after 15 minutes (23ºC / 50% r.h.)
Full cure after 12 hours
-40ºC to +80ºC (temporary up to +100ºC)
Approx. 0.04 W/mK
Mechanical / Physical Properties
3N/cm2 at 10% strength (+23ºC / 50% r.h.)
3N/cm2 (+23ºC / 50% r.h.)
8N/cm2 (+23ºC / 50% r.h.)
Elongation at Break
18% (+23ºC / 50% r.h.)
750 ml can up to 55 litres (± 3 litres)
Clean homogenous free from oils and grease dust and loose or friable particles.
Pre dampen the substrate with clean water this ensures that the foam cures optimally and also prevents secondary foam expansion later on.
Application Conditions / Limitations
+5ºC min. / +30ºC max
Optimum handling temperature +18ºC to +25ºC
Permissible handling temperature +5ºC min / +30ºC max.
Relative Air Humidity
Between 30% and 100%
Shake the can thoroughly before use (~ 20 times)
Remove the small black lid from the Sika Boom®-FR aerosol can. Screw the Sika Boom®-FR nozzle onto the can. Gently press the trigger.
Take care to allow each layer to cure sufficiently by spraying water or allowing sufficient waiting time between the layers.
Do not fill up hollow sections completely as the foam expands by 1.5 to 2 times its volume during curing.
All fixings and components etc must be temporarily supported until the foam has hardened.
Cleaning of Tools
Remove fresh spots of foam immediately using a cleaner such as Sika Boom Cleaner. Cured foam can only be removed mechanically.
Notes on Application / Limitations
The aerosol can temperature has to be +5ºC min. and +25ºC max. For optimum flow and expansion the aerosol can temperature should be +18ºC to +25ºC.
Protect the can from direct sun and temperatures above +50ºC (danger of explosion). For the correct curing of the foam sufficient moisture is necessary.
Do to use on PE PP Teflon Silicone Oil Grease and other separating agents.
Foam is not resistant to UV light.
Read the safety and technical recommendations printed on the aerosol can.
To avoid rare allergic reactions we recommend the use of protective gloves. Change soiled work clothes and wash hands before breaks and after finishing work.
Local regulations as well as health and safety advice on packaging labels must be observed.
For further information refer to the Material Safety Data Sheet which is available on request.
If in doubt always follow the directions given on the pack or label.
Residues of material must be removed according to local regulations. Fully cured material can be disposed of as household waste under agreement with the responsible local authorities.
Detailed health and safety information as well as detailed precautionary measures e.g. physical toxicological and ecological data can be obtained from the Material Safety Data Sheet.
