Description

Alfas Bond FR is a one-component polyurethane (PU) foam, packaged in aerosol form for in-situ application. The propellants used are CFC and (H)CFC free and have a zero ozone depletion potential. The product expands and cures on application through the absorption of moisture from the atmosphere. The cured foam has a substantially closed cell structure throughout and hardens to a semi-rigid form which is both firm and yielding and yet can be trimmed using a sharp knife.

Alfas Bond FR is available in two types of canister: In-situ Grade (dispensed via a plastic nozzle) and a Gun Grade (for use with the Alfas Bond FR Application Gun). A dual purpose solvent and spray cleaner (Webbflex PU Foam Solvent Cleaner) is available for cleaning the guns and ancillary equipment, details are available upon request from the Sales office.

Typical Uses
Alfas Bond FR has excellent adhesive properties and once set, forms a strong bond to most building materials such as wood, brick, stone, cement, plaster, polystyrene, metals and many plastics. The product acts as a fire seal for up to 4 hours when tested to BS 476 Part 20 or for longer periods when used in conjunction with Alfasil FR, FR-2 or Alfacryl FR.
