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.
