Product Description

Name	SV-304
Base	Polyurethane
Consistency	Stable Foam
Volume	750ml
weight	900g

 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.

High foaming capacity, caulk length of 24 meters,foam delicate,No expansion before the foam,No expansion before the foam,reduce waste.Good elasticity,Improve the seismic resistance of doors and windows.

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.

Feature

1.Low Foam Pressure/Low Expansion - will not warp or deform windows and doors
2.Quick Setting Formulation - can be cut or trimmed in less than 1 hour
3.Closed Cell Structure does not absorb moisture
4.Flexible/Will not crack or dry out

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.
