ESPUMA POLIURETANO IGNÍFUGA COMPACT 750ML SPRAY

Compact 750 ml Fire-Retardant Polyurethane Foam Spray is designed to fill and seal gaps in building components where specific fire-resistant properties are required. It is a single-component, self-expanding foam that cures by reacting with ambient moisture.

Alfa Dyser specifies fire resistance rating EI 240 according to EN 13501-2 and classification B1 in accordance with DIN 4102-1, achieving up to 4 hours of fire resistance under the corresponding conditions. It also provides thermal and acoustic insulation once cured.

The 750-ml aerosol can includes a manual applicator and can be used on wood, concrete, brick, stone, plaster, and metal. After curing, it acquires a semi-rigid texture that allows it to be cut, shaped, sanded, and subsequently painted or coated according to the desired finish.
