Product Description
Product description:
SV-304 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.
Product 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

Application
Product Applications:
1.Application where fire retardant properties are required;
2. Installing, fixing and insulating of door and window frames;
3. Filling and sealing of gaps, joint, openings and cavities;
4. Connecting of insulation materials and roof construction;
5. Bonding and mounting;
6. Insulating the electrical outlets and water pipes;
7. Heat preservation, cold and sound insulation;
8. Packaging purpose, wrap the precious & fragile commodity, shake-proof and anti-pressure
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 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
