What is Froth-Pak PU foam?

Froth-Pak is a sprayable PU foam with a closed cell structure for perfect insulation. Dupont Froth-Pak has a high insulation value and adheres to almost any surface. Due to the unique system, you don't need pumps, compressors or other machines to use Froth-Pak. Heat the cylinders, simply connect the hoses together and you are ready to process the sprayable PU foam!

  • Very fast curing.
  • Easy to work with after curing (10 minutes).
  • No more condensation on your walls and therefore no rust formation.
  • Fire retardant.
  • Suitable for vertical and overhead application.

What do you need to process Froth-Pak?

When using insulation foam, it is necessary that you have the right products at home. At Polyestershoppen you will find all the necessary materials to be well prepared to get started with the sprayable PU foam from Froth-Pak. Always use the following products:

Froth-Pak Instructions 

Follow these steps while processing Froth-Pak:

Step 1. Preheat the Froth-Pak set

Good preparation is very important when you start working with Froth-Pak. Therefore, make sure you have the right materials at home.

For proper functioning of the foam with maximum efficiency, it is necessary to preheat the Froth-Pak set. Therefore, ensure that the temperature of the cylinders is at least 24°C but at most 40°C. Is the temperature of the packaging too low? It may then happen that one of the pipes becomes clogged, causing the PUR foam to be of lower quality or not even harden. Therefore, always use a  Froth-Pak heating jacket (even in the summer months).

Start preheating on time. It can take quite a while before the contents are really warm. We recommend turning on the heating mantle at least a day in advance.

Step 2. Prepare the workplace (mask off)

Prepare the space you are going to insulate well and mask off everything that you do not want PU foam on. Use protective foil and masking tape for this. In addition, make sure that the room is dry and grease free. It is not possible to spray PU on a damp surface or on a surface with condensation or grease residue.

Step 3. Put on the correct protective clothing

Once cured, Froth-Pak is completely safe. However, it is important to protect yourself well during processing. Therefore, always work safely and use the correct personal protective equipment when working with polyurethane foam.

Always wear old clothing, (disposable) overalls with a hood, safety glasses, gloves and a vapour mask with A2 filters.

Tip: with the Froth-Pak safety package you immediately have all the necessary safety materials at your fingertips!

Step 4. Connect the Froth-Pak set

Are the cylinders preheated, is the area masked off and are you wearing the correct protective equipment? Then you continue with connecting the Froth-Pak set. Follow the following steps:

  • Connect both hoses to the correct cylinder using the indicated color (red to red, blue to blue).
  • Tighten the nut of the hose set using the supplied wrench.
  • Open the cylinders fully.
  • Spray the application gun with Vaseline spray or lubricate it with a tube of Vaseline.
  • Flush the pipe thoroughly by spraying it several times at full power into a garbage bag (without nozzle).
  • Clean the inside of the gun with PU cleaner.
  • Click the nozzle into the application gun. You will hear a click indicating that the nozzle is firmly attached. 

The set is now ready for use!

Step 5. Apply an adhesive layer

First apply a thin adhesive layer to the surface. This ensures that the next layer adheres better. Use a quick, sweeping motion to apply a thin layer. Use a blue nozzle to apply the adhesive layer.

Please note: PU foam must start foaming immediately. If this does not happen within 60 seconds, there is a chance that one of the pipes is clogged. Then first spray without a nozzle into an empty garbage bag for a few seconds to thoroughly flush the pipes. Attach a new nozzle and continue spraying. If in doubt, do a test first.

Step 6. Apply an insulating layer

Once you have provided the surface with an adhesive layer, continue by applying a thick insulating layer of approximately 5 cm.

Connect a new white nozzle and treat the surface again. It is possible to apply this layer with a blue nozzle if you prefer to work in thin layers. Spray in a slow, sweeping motion to create a thick layer of insulation. This way you spray approximately 1 to 1.5 cm thick. Only spray the next layer after a few minutes once the first layer has hardened.

Replace the nozzle as soon as you notice that it produces less output. Then less PU comes out of the gun. If you replace the nozzle, you will immediately notice a difference! Also replace the nozzle if you stop spraying for more than 30 seconds because the nozzle becomes clogged by the solidifying polyurethane foam.

Keep an eye on the colour of the foam. Does the foam suddenly turn white? Then the ISO pipe is clogged (the red pipe). Remove the nozzle, spray briefly and install a new nozzle. Test regularly whether the foam hardens properly.

Please watch our Trouble shooting video with useful tips for solving problems.

Step 7. Finish the area

Have you treated the entire space with a thick layer of PU foam? Then you let the material harden for an hour. Make sure you continue to ventilate the room well in the meantime. After an hour, remove all tape and covering foil. You can easily remove excess PU foam with a saw, snap-off knife or putty knife. Now finish the insulated space as desired.

Handy Tips & Tricks

 

Tip 1. Make sure you cover and mask the area properly

Prepare the area and cover it properly. Tape the protective foil securely so that you cannot accidentally pull it off.

Tip 2. Keep all important materials within reach

Make sure that you always have a number of important materials within reach during processing. This way you don't waste time searching if you suddenly need them. Always keep the following materials within reach:

  • New nozzles.
  • New gloves.
  • PU Cleaner Vaseline Spray.
  • Garbage bag or cardboard box to inject a sample into.

Tip 3. Choose the right nozzle

Choose the right nozzle for spraying the PUR foam. The nozzles have different colors and are for different applications:

  • White nozzle [medium]
    Most used and versatile nozzle for all-round applications.

  • Blue nozzle [medium/fine]
    Use the blue nozzle for applying thin (fine) layers such as adhesive layers.

  • Green nozzle [small]
    This small nozzle is used for the controlled application of strips of insulation foam.

  • Black nozzle [large]
    Use the black nozzle for filling large cavities. High capacity spraying.

Make sure you always order enough nozzles so that you don't run out. 

Tip 4. Remain calm

Relax and stay calm while working with Froth-Pak. Read carefully, make a plan in advance and don't let time pressure rush you. This way you work in a structured way and you can easily deal with setbacks, such as blockages.
