FM330 - Manual and gun-applied elastic PU foam - Illbruck

FM330 is a single-component elastic polyurethane foam that expands and hardens by absorbing moisture from the air.

It is characterized by a high degree of elasticity of 50% and low post-expansion, thus greatly reducing the pressure exerted on the supports.

It is a professional-grade expanding foam, suitable for all surfaces encountered in construction: concrete, masonry, stone, plaster, wood, cement and mineral fiber concrete, polystyrene, polyester, rigid PVC...

For filling cavities, we recommend manual use with the nozzle; if more precise use of the foam is required, the aerosol can be screwed onto an expanding foam gun such as the illbruck AA230, AA250 and AA270 guns.

Advantage :

• Aerosol equipped with a 2-in-1 system: can be used with a gun or manually.
• 360° all-around use thanks to the conical nozzle.
• Low post-expansion: does not develop pressure, thus avoiding deformation of supports.
• 50% elasticity.
• Can be applied at low temperatures (down to -3°C).
• Easy to cut after polymerization.
• Can be painted.

Preparation :

• FM330 must be used at an ambient temperature between -3°C and +35°C. The aerosol must be at a temperature between +5°C and +30°C.
• The surfaces must be solid, dust-free and grease-free.
• Moisten the bonding surfaces to obtain a foam with a homogeneous cellular structure and faster hardening.
• Shake the aerosol can well 20 to 30 times before using.

Implementation:

Manual:

• Remove the protective cover from the top of the aerosol can.
• To dispense the foam, gently press the valve; the amount of extruded foam can be controlled by adjusting the lever on the valve.
• Fill the cavities to 80% to leave room for foam expansion.
• For large cavities (more than 5cm deep), it is best to apply the foam in several layers and moisten between each layer (wait 30 minutes between each layer).

Pistolable:

• Remove the protective cover from the top of the aerosol can.
• Screw the aerosol can fully onto the gun.
• Control the extrusion by lightly pressing the trigger on the gun and adjust the quantity with the adjustment screw.
• Fill the cavities to 90% to leave room for foam expansion.
• For large cavities (more than 5 cm deep), it is best to apply the foam in several layers and moisten between each layer (wait 30 minutes between each layer).

Hygiene and safety precautions

• Work only in well-ventilated premises.
• NO SMOKING.
• Wear protective clothing.
• Protect your eyes and wear protective gloves.
• Protect the work area extensively with paper or a plastic sheet.

Cleaning:

• After use, quickly clean with illbruck AA290 cleaner either the valve and nozzle (for manual use), or the outside of the gun and its nozzle (for gun use).
• Hardened foam can only be removed mechanically (using a utility knife, sanding with sandpaper, etc.). Therefore, it is strongly advised to protect floors with plastic sheeting or paper in the work areas.

Packaging:

• 2-in-1 aerosol can of 880 ml.

FAQ - Frequently Asked Questions

1. Is FM330 foam truly elastic after drying?
   Yes, unlike conventional PU foams, FM330 retains lasting flexibility, allowing it to follow the movements of the supports without cracking.
2. Can it be used for installing windows and doors?
   Yes, that's one of its main applications. It's ideal for perimeter joints of joinery subject to expansion and vibration.
3. Is it compatible with a foam gun?
   Yes, the FM330 can be used in manual mode or with an applicator gun, depending on the type of aerosol and equipment chosen.
4. Can the foam be painted after it has dried?
   Yes, once completely hardened, the foam can be cut, sanded and painted with most common paints.
5. Is it suitable for outdoor use?
   Yes, provided that it is protected from UV rays (paint, sealant or coating), like any polyurethane foam.
6. What types of media does it support?
   It adheres very well to concrete, brick, wood, metal, rigid PVC and most common building materials.
7. Is it suitable for thermal and acoustic insulation?
   Yes, the FM330 offers good thermal and acoustic insulation performance, especially around window and door frames.
