Fireproof Polyurethane Foam

Short Description:

SIWAY FR PU FOAM is multi purpose, filling and insulation foam which carries DIN4102 standards. it carries fire retardancy(B2). It is fitted with a plastic adapter head for use with a foam application gun or a straw. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation. It is environmental friendly as it does not contains any CFC materials.

Product Description

PRODUCT FEATURES
1.B2 fire rating.
2. Strong surfaces after cured.
3. High yield-up to 50L.

APPLICATIONS AREAS
1. Flxing and insulating of door and window frames.
2. Insulating of pipes and filling of holes and gaps .
3. Fulling of joints and installation of electrical wiring.
4. Fixing and insulating wall panels. corrugated sheets.

APPLICATION INSTRUCTIONS
1. Remove the dust, greasy dirt on the surface before construction.
2. Spray a little water on construction surface when the humidity is below 50 degrees, otherwise the heartburn or punch phenomenon will appear .
3. The flow rate of the foam can be adjusted by the control panel.
4. Shake the container for 1 minute before using, connect material container with spray gun or spray pipe, the filler content is 1/2 of the gap.
5. Use dedicated cleaning agent to clean the gun Surface drying time is about 5 minutes, and it can be cut after 30 minutes, after 1 hour the foam will be cured and achieve stable in 3-5 hours.
6. This product is not UV-proof, so it is suggested to be cut and coated after the foam curing (such as cement mortar, coatings, etc.)
7. Construction when temperature is lower than -5℃, to ensure the material can be exhausted and increase the foam expansion, it should be heated by 40 ℃ to 50 ℃ warm water
