Description

Everbuild B2FIREGUN Fire Foam B2 Gun Grade Aerosol 750ml

Everbuild EVBB2FIREGUN firefoam B2 is a quick setting one part polyurethane foam with fire resistant properties. The foam expands on application to up to 50 times its original volume and meets the requirements of DIN 4102 Part 1 for Construction Materials; Class B2.

Once cured, the foam can be cut, sawn or plastered over after only one hour providing the working temperatures (can and surfaces) are between +5 to +25oC, ideally 20 Degrees Celsius. High degree of fire rating: slows down the passage of flames and smoke in comparison to standard B3 grades. Quick setting - can be cut, sawn or plastered in 1-hour is economical in use as it will expand up to 50 times its original volume.
