Gap Filling Expandable PU Foam Spray Sealant - What is it?

Gap filling Expandable PU Foam spray Sealant  is dispensed as a frothy liquid which expands and moisture-cures into a solid foam insulation and sealant. Being a one-component, foam sealant is used to fill and seal small cracks and voids such as around door and window frames, sill plates, electrical devices where air leakage and energy loss can occur. Formulations are available for general use and specific applications such as sealing windows and doors, fire blocking, and construction adhesive.

Type of Foam Spray Sealant

PU Insulating Foam  Sealant is generally made available in two forms – types of PU foam

  • 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 
Furthar it is classified into B3 ( Non FR ) type and B1( FR ) type PU foam spray.
 

Using Spray Can- Foam spray sealant

Supex 100 straw type

  1. Clean the application area with water spray.
  2. 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.
  3. 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.
  4. Attach the Straw on the can.
  5. Shake the can vigorously  for 20 to 25 times.
  6. Hold the can upside down such that the valve faces downwards. This is the only way to completely empty the can.
  7. Press the trigger, foam will rush out of the can under pressure.
  8. Keep shaking the can.
  9. 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.
  10. The foam cures in 30 – 40 minutes depending upon weather conditions.
  11. After curing , extra foam can be cut with a sharp knife.
  12. 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.

Using Gun Grade foam spray sealant

  1. PU Foam Spray SealantClean the application area with water spray.
  2.  Moisten the area using the same water spray. Foam sealant adheres to substrates that are  clean and free of dust and grease.

3. Surface must be dampened enough to ensure that the water sprayFoam sealant finds adequate moisture for its hardening process.

4. Attach the gun on the spray can, hold the gun such that the can is upside down .

5. Adjust the knob at the end of gun to control dispensing speed/ quantity. Press gun trigger for application.

6. Keep shaking the can.

7. Gun mounted  can be used and stored for a day or two , provided the tip of gun is sealed from moisture – using grease etc.

8. The foam cures in 30- 40 minutes depending upon weather conditions.

9. After curing, extra foam can be cut with a sharp knife.excess foam cutting after drying

10. PU foam sealant is paintable. However, it is not UV resistant – should not be exposed to direct sunlight. If unavoidable – paint the foam to protect from sunlight.

11. After emptying  the can , mount the PU cleaner – press  till entire foam is extruded from the gun and the gun is free from foam .

12. Gun and cleaner can be removed and stored till next usage.

Applications of Foam Spray Sealant

  • Filling of joints, seams and cracks in partition walls with ceilings.
  • Structural space between window and door frames and walls.
  • Structural and fitting space between prefabricated construction elements
  • Around cables and pipes, penetrations through walls and ceilings.
  • Gluing panels/ insulating sheets.
