41 07 100 Notes On Cavity Foam

Warning:
- Cavity foam is damaging to health and highly flammable!:
- Empty the can completely immediately after use. Foam material set even in the can. There is therefore a danger of bursting as a result of foam expansion, even when the can is partly empty.

Protection measures:
- Wear protective goggles
- Wear solvent-resistant protective gloves

Recycling:
Not fully emptied and unused cans with elapsed expiry dates must be treated as special waste.
Foam which has set can be disposed of as residual waste.
Observe country-specific waste-disposal regulations.

Important:
- Do not fill cavity completely (risk of damage).
- Foam expands while it sets by several times over (volume change). Setting takes approx. 30 minutes. Mechanical processing (e.g. drilling, cutting, etc.) is then possible.







Note on mixing:
- Perform activation at room temperature only.
- Foam material has two components and must be activated prior to use in the can.
- The operations pictured on the can must be carried out for this purpose.
- Activated cavity foam can be used when the foam colour is uniform.
- The application time is approx. 5 minutes. The cavity foam must be introduced within this period.
