Description & use
Piro Foam PF 240 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 or with a tip adapted to a dispensing gun. The foam hardens by absorbing moisture from air.
Piro Foam PF 240 is designed for fireproof sealing:
• gaps, expansion joints in building partitions constituting fire partitions with a possible displacement of up to ± 7.5%,
• space between steel structure and partition,
• spaces between frames and window and door frames (wooden, steel, PVC) - the foam does not replace the mechanical fastening of windows and doors to the building partition,
• ideal for filling large, irregular and difficult-to-fill gaps, increasing their volume, fills them completely.
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 facades, e.g. cement mortar, gypsum mortar, fire-resistant acrylic mass, PiroCoat A ablation paste 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.
