Bond It B1 FIRE RESISTANT EXPANDING PU FOAM Gun Grade Pink 750ml
A high performance, polyurethane expanding foam, fire rated and tested to BSEN 1366-4 and BS476 Part 20 (the most stringent test for fire-rated products). Seals irregular gaps and expands over 40 times its can volume. This foam can be used at temperatures from +5°C to +25°C. The cured foam is semi-rigid and predominantly close-celled. It is resistant to temperatures ranging from -40°C to +100°C and to ageing, but not to UV-rays. Noise and heat insulation values are excellent. Available in gun grade or straw aerosol version.
The fresh foam adheres to all common building materials except surfaces such as polyethylene, silicone, oil and grease and similar substrates.
Areas Of Application:
- Window setting (where a clean and controlled.
- Roller shutters (sealing of connection joints).
- Entrance door linings.
- Any kind of small breakthroughs in walls and other cavities.
The foam can be used at temperatures from +5°C to +25°C. The cured foam is semi-rigid and predominantly close-celled. It is resistant to temperatures ranging from -40°C to +100°C and to ageing, but not to UV-rays. Noise and heat insulation values are excellent. This foam meets the requirements of the Construction Materials Class B1 rating in accordance with DIN 4102 Part 1.
Surfaces to be bonded must be firm, clean, dry and free from dust, grease or contaminants that may hinder adhesion. They must be moistened well with water. It is advisable to apply a primer well penetrating into the ground if necessary. All construction components must be properly prepared prior to foam application. It is advisable to have
Foam Cleaner at hand. The ideal working temperature for both the can and environment is +20°C. Chilled cans must be carefully warmed in luke-warm water before usage. However, the can must not be heated above +50°C, as there is
a risk of bursting. Cans which are too hot, for example after having been left in a vehicle during summer, must be cooled in water. The can should be shaken occasionally during this process to obtain the required temperature faster.
Prior to work, and before the adaptor is attached, the can must be shaken thoroughly at least 15 – 20 times. Then the adaptor is attached firmly to the valve. Care must be taken not to overtighten the adaptor and not to activate the valve during this process.
How To Use
- The instructions for the can must strictly be observed.
- The fresh foam will expand by 1 ½ to 2 times.
- Therefore care must be taken not to overfill joints.
- Fresh foam spills must be removed immediately within the tack-free time with Foam Cleaner.
- Cured foam must be removed mechanically.
Please Note: Moisture is needed for an even and rapid curing of the foam. Inadequate moistening or overfilling of
joints and cavities may lead to an unwanted post-expansion of the foam. Foam extrusion can be controlled accurately by varying the pressure or by tilting the adaptor. For foam extrusion, the valve is pointed down. The valve lever is to be activated carefully. Once a can has been started, it should be used within four weeks.
