Expanding PU Foam Spray Sealant
Expanding Foam spray Sealant is generally made available in two forms –
- Spray Can – Dipensed using an adopter or straw or Pipe : one straw is preattached to the can .
- Gun grade – Dispensed using a Hand held PU Gun
How to use Expanding foam spray sealant
- Clean the application area with water spray.
- Moisten the area with Water spray. PU foam adheres to almost all surfaces that are strong, clean and free of dust and grease. Only silicon, oils, greases, polyethylene, teflon or similar surfaces are not suitable to be applied on.
- Surface must be dampened enough to ensure that the foam sealant finds adequate moisture for its hardening process. Otherwise, it could impair the adhesion and edge adhesion.
- Attach the Straw on the can.
- Shake the can vigorously for 20 to 25 times.
- Hold the can upside down such that the valve faces downwards. This is the only way to completely empty the can.
- Press the trigger, foam will rush out of the can under pressure.
- Keep shaking the can.
- Plan the work such that entire can material is consumed in one go, i.e., after opening the can, it should be completely consumed. This is recommended because whatever is left will get cured inside the can and thus go to waste.
- The foam cures in 30 – 40 minutes depending upon weather conditions.
- After curing , extra foam can be cut with a sharp knife.
- Foam sealant is paintable. It is not UV resistant – should not be exposed to direct sunlight. If unavoidable – paint the foam to protect from sunlight.
