Bond It MEGA FOAM PU EXPANDING FOAM Aerosol 500ml Beige
A high performance, polyurethane expanding foam available for use as an aerosol grade using a patented adaptor or by simply fixing a gun applicator can be used as a gun grade. Quick, economical and easy to apply for fitting doors, windows and insulating pipes and filling gaps. Improves draught and heat insulation and deadens noise. Fitted with a new, unique valve which allows for multi-directional use.
- Can be used at any angle through 360°
- High yield up to 30% more volume than standard foam
- Longer shelf life than that of a standard can
- Problem-free valve
- Fills holes and seals gaps
- Exceeds DIN4102 Class B3 (Foam rating for products with no fire-resistant additives or properties).
Window setting (where a clean and controlled backfill is required), entrance door linings, any kind of small break-throughs 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.
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 a 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 or gun is attached, the can must be shaken thoroughly for at least 30 seconds to mix the contents. 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 1½ 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 on the adaptor or gun trigger. For foam extrusion, the valve is best pointed down, but it will work through 360degrees. The valve lever is to be activated carefully. Once a can has been started, it should be used within four weeks.
