Nottefoam 840

Description

High efficiency polyurethane gun foam for professional users, easily dosed with an application gun. Resistant to humidity and mold, it provides a long life semi-hard filling material.

Usage Areas

Filling and insulating gaps around window and door frames.
Filling penetration gaps of pipes belonging to gas, water, electricity installations.
Filling and insulating irregular gaps, cracks, and holes in buildings.

Characteristics

High yield foam allows to fill higher number of doors and windows.
Application with a gun—a allows easier and more controllable dosage.
Controlled expansion, low pressure on door and window frames.
Cures fast, becomes cuttable within half an hour.
High stability, no shrinkage.
Non-sag on vertical substrates.
Re-usable if the applicator gun left on the can.
Strong adhesion on common building materials.

Application Method

Application surfaces must be clean and dry and not contain oil, rust, and loose parts.
Slightly wetting the surfaces might increase performance of foam and make it dry faster.
Surrounding of application areas where foam shall not be applied may be covered for protection purposes.

Bring aerosol can to room temperature.
Ambient temperature should be +10°C to +30°C.
Shake the can vigorously before attaching the straw.
Attach the straw to the valve by twisting.
While the can is upside down, press the trigger for the foam to come out.
Since the foam would expand, fill the gaps partially.
Too big gaps should be filled in two layers and top of foam should be wetted.
Continue to shake the can from time to time during application.
Leave the straw for the next application, otherwise clean the valve with a solvent like acetone.
Fresh foam can be cleaned with foam cleaner or a solvent like acetone.

Consistency: non-sag
Application temperature: +5°C to +40°C
Set time (initial / for contact): min. 20 minutes Set Time
Set time (formation of surface film): min. 35 minutes

Consumption

Changes according to application type and surface.

Packaging and Storage

840g (750ml) Aerosol cans (16 canisters in a box)
Pipette & Gun Applied
12 months shelf life when stored in a cool and dry environment in an upright position between 10°C and 30°C.

Safety Precautions

To protect from direct sunlight, the foam must be painted or covered with a sealant. It is not possible to provide strong adhesion on teflon, PE, and PP plastics.
Contains difenylmethane-4,4-diisocyanate which can cause sensitivity on respiratory organs if inhaled for long periods. It may cause local rash and sensitivity on the skin.
The environment should be well-ventilated during the application, contact with the skin should be avoided, and protective gloves and safety goggles should preferably be worn.
