FM330 - Manual and sprayable elastic PU foam - Illbruck

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

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

It is an expansive foam of professional quality, which is suitable on all supports 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 expandive foam gun such as the illbruck AA230, AA250 and AA270 pistols.

Advantage: 

• Aerosol equipped with the 2-in-1 system: pistolable or manual use.
• Use in all directions 360 ° thanks to the conical nozzle.
• Low post-expansion: does not develop pressure, thus avoiding deformations of the 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 supports must be strong, dusted and degreased.
• Moisten the adhesion surfaces to obtain a foam with a homogeneous cell structure and faster hardening.
• Shake the aerosol well 20 to 30 times before use.

Implementation: 

Manual: 

• Remove the protection at the top of the aerosol.
• To bring out the foam, press lightly on the valve; the amount of extruded foam can be dosed by more or less actuating 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 better to apply the foam in several layers and moisten between each layer (wait 30min between each layer).

Pistolable: 

• Remove the protection at the top of the aerosol.
• Screw the aerosol thoroughly onto the gun.
• Dose the extrusion by lightly pressing the trigger of 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 better 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.
• Do not smoke.
• Wear protective clothing.
• Protect the eyes and wear protective gloves.
• Largely protect the working area with paper or plastic sheet.

Cleaning: 

• After use, clean quickly with the illbruck AA290 cleaner either the valve and nozzle (for manual use) or the outside of the gun and its tip (for pistolable use).
• The hardened foam can only be removed mechanically (cutter, sanding with sandpaper...). It is therefore strongly recommended to protect the floors, with plastic film or paper in the work areas.

Conditioning: 

• Aerosol 2 in 1 of 880 ml.
