- Product End Uses
- Implementation
It is the responsibility of the installer and/or operator to ensure that the uses described in the report correspond to the regulatory requirements for the application planned.
Preperation
- Use appropriate gloves and protect the surrounding surfaces (the foam once hardened can only be removed mechanically).
- Substrates must be clean and dust free. Moisten them to obtain a foam with a more homogeneous structure and faster hardening.
- The application temperature must be between +5°C and +35°C.
- Calculate the amount of foam required (see the consumption paragraph below).
Manual
Manual version:
- Remove the cover and attach the extruder nozzle to the valve.
- Turn the aerosol upside down and shake vigorously at least 20 times before use.
- Apply the foam by holding the aerosol upside down.
- Fill the cavities partially, the foam expanding several times its initial volume. The foam, once injected, must always have at least one side in contact with the ambient air. In the case of deep cavities, proceed by successive injections, spaced approximately 1 to 2 hours apart, over 5 cm at a time and moistening in between.
- In order to allow the aerosol to be reused without having to clean it, fold the cannula back on itself and attach it to the nipple for use within three weeks.Otherwise, immediately clean the nozzle and the valve of the aerosol using the 2 IN 1 PU FOAM CLEANER.
- Cut the excess hardened foam (cutter, saw blade for example). The complete drying of the foam will be done within 24 hours.
Pistol version:
- Shake vigorously at least 20 times before use.
- Apply the foam by holding the aerosol upside down.
- Fill the cavities partially, the foam expanding several times its initial volume. The foam, once injected, must always have at least one side in contact with the ambient air. In the case of deep cavities, proceed by successive injections, spaced approximately 1 to 2 hours apart, over 5 cm at a time and moistening in between.
- The aerosol on the gun can be stored for 4 weeks provided that the gun flow adjustment knob is completely screwed in and the remaining fresh foam is cleaned with PU FOAM CLEANER 2 IN 1. Otherwise, immediately clean the interior and the exterior of the gun, as well as the aerosol valve using PU FOAM CLEANER 2 IN 1 (pay attention to the pressurized solvent remaining in the gun after cleaning).
- Cut the excess hardened foam (cutter, saw blade for example). The complete drying of the foam will be done within 24 hours.
Consumption
Free-expanding filling capacity: up to 45 l for a 750 ml aerosol.
Equipment cleaning
The equipment is cleaned with the 2 IN 1 PU FOAM CLEANER before the foam dries or by scraping after hardening.
- Applications
Caulking of vertical linear joints without crossing.
- Use
Upside down
