Applications & Uses
- Markets
- Applications
- Caulking.
- Heat and sound insulation.
- Insulation and wedging of pipes.
- Filling of cavities and bleedings.
- Brings the advantage of delaying the spread of fire by igniting with difficulty.
- Implementation
Preperation
- Use appropriate gloves and protect the surrounding surfaces (the foam once hardened can only be removed mechanically).
- The aerosol must be at room temperature (between +20°C and +25°C) and the substrates at a temperature above +5°C.
- Work surfaces must be clean, degreased.
Manual
- Remove the cover and attach the extruder nozzle to the valve.
- Turn the aerosol upside down and shake vigorously about 20 times before use. Apply the foam by holding the aerosol upside down.
- Fill the cavities partially, the foam expanding several times its initial volume. The foam, once injected, must always have at least one side in contact with the ambient air. In the case of deep cavities, proceed by successive injections, spaced approximately one hour apart, 5 cm at a time.
- Cut the excess hardened foam (cutter, saw blade for example). The foam can be covered with a paint or coating (plaster, plaster, wallpaper, etc.). The foam remains sensitive to UV as long as it is not protected.
Consumption
Filling capacity in free expansion: 35 l for the 750 ml.
Equipment cleaning
After use, disassemble the extruder spout and carefully clean all parts (valve, spout and nozzle) with 2IN1 PU FOAM CLEANER. Tools and soiled surfaces can also be cleaned with this same product or, failing that, with acetone (check compatibility with surfaces).

Regulatory & Compliance
- Regulations
GEB has equipped its range of PU foams with gloves and labeling in compliance with the regulations in force.
- Labels and Approvals
Reaction to fire classification according to DIN 4102-1: B1
This German standard classifies polyurethane foams according to their reaction to fire. A foam classified B1 is more difficult to ignite than a standard foam and therefore slows the spread of flames.
Technical Details & Test Data
- Tricks
Surfaces can be moistened to speed up the curing process and improve adhesion.
- Comments
- The foam once hardened can only be removed mechanically.
- Propellent gas respecting the ozone layer, CFC and HCFC free.
Safety & Health
- Warning
Dangerous, respect precautions.
Storage & Handling
- Storage
Store at a temperature between +10°C and +20°C. The expiry date noted on the packaging is measured on the unopened product, stored at 20°C under normal humidity conditions.
