FP Foam

 
Performance Benefits

* Fire protection for up to 4 hours to BS 476 Part 20
* Expands to 40 times the can volume
* Low cost bulk filler
*  Bulk filling of irregular voids
* Excellent adhesion
*  Good sealing and insulation properties
* One component - fast curing
* CFC and (H) CFC free
* PU Foam

A one component PU foam which expands in-situ to fill and seal gaps. The foam cures rapidly through absorption of moisture from the atmosphere and can be trimmed or sanded within an hour. FP Foam forms a strong bond to most building substrates such as wood, brick, stone, cement, plaster, metals, polystyrene and many plastics. The cured foam has a substantially closed cell structure throughout. It hardens to a semi-rigid form which is both firm and yielding (approximate movement accommodation +/- 5%)

In-Situ 8c Gun Grades

Available in two types: an In-Situ Grade (dispensed via a plastic nozzle) and a Gun Grade (for use with a Metal or Plastic Applicator Gun). A dual purpose solvent spray cleaner is available for cleaning guns and ancillary equipment.

Storage, Handling, Application

No special surface preparation or primers are required but surfaces in contact with the product must be clean of loose matter, grease or oils. FP Foam will not adhere to Teflon, polythene or silicone coated surfaces. Loose components may need to be clamped or secured in position at least until the foam sets. Surrounding surfaces should be suitably fpfoam1.jpg (14379 bytes)

masked and protective clothing worn. The canister must be well shaken to thoroughly mix the contents and must be inverted during use. The Gun Grade allows greater control on application and permits the storage (for short periods of time) of partially used canisters. Care should be taken upon application to allow for expansion of the foam during curing. Where gaps deeper than 50mm are to be filled, the FP Foam must be applied in layers allowing each to cure properly. Within the first few minutes of application, splashes of material may be removed from unwanted (non-porous) surfaces using a suitable solvent. However, care should be taken to ensure that the solvent used will not stain or attack the surfaces onto which it is being applied. The yield and rate of cure will vary according to temperature and humidity. Curing will be assisted by wetting the contact surfaces immediately prior to application. Once fully cured, FP Foam can only be removed by mechanical means. Excess material may be trimmed off using a sharp knife or sanded down. The cured foam is not resistant to UV light and should be protected using FR Silicone Sealant, IFP Intumescent Acrylic Mastic or a suitable fire rated paint.

FP Foam acts as a fire seal in accordance with BS476 Part 20 (see below) and meets Class B1 of DIN 4102 Part 1.
