SIWAY PU FOAM is a one-component, economical type and good performance Polyurethane foam. 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.

The product is the expansion,moisture curing,has the strong conhesiveness,elastic foam obturator structure;save work to save time,reduce waste;high bond strength;
Bubble can stick in the concrete,wood,metal,plastic,such as base material surface,but not including teflon,silicone resins.

Technical data
How to use it
Remove the dust, greasy dirt on the surface before construction.
* Spray a little water on construction surface when the humidity is below 50degrees, otherwise the heartburn or punch phenomenon
will appear .
* The flow rate of the foam can be adjusted by the control panel.
* 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.
* 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.
* 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.)
* Construction when temperature is lower than -5 ºC, to ensure the material   can be exhausted and increase the foam expansion, it   should be heated by 40 ºC to 50 ºC warm water.
