Description & use
PIROFOAM 240 W is a one-component, semi-rigid polyurethane spray foam. It is supplied in a liquid state in a 750 ml spray in a version with a flexible application by straw. The foam hardens by absorbing moisture from air.
PIROFOAM 240 is intended for fireproof sealing:
• Horizontal expansion joints in building partitions constituting fire partitions with a possible displacement of up to ± 7.5%
• Vertical expansion joints in building partitions constituting fire partitions with a possible displacement of up to ± 7.5%
Works with the use of foam are carried out at a temperature of + 5 ° C to + 30 ° C. The product should not be exposed to direct effects of external weather conditions. The foam is not resistant to UV radiation, it should be protected against its effects by covering it with a suitable material intended for use on building walls e.g. cement mortar, fire-resistant sealing silicone PIROSILICON 240 or topcoat paint. The time required for the foam to fully cure and volatile flammable components to evaporate in order to achieve full fire resistance is 14 days.
