It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation.

APPLICATIONS AREAS

lInstalling, fixing and insulating of door and window frames.

lFilling and sealing of gaps, joint, openings and cavities.

lConnecting of insulation materials and roof construction.

lBonding and mounting.

lInsulating the electrical outlets and water pipes.

lHeat preservation, cold and sound insulation.

lPackaging purpose, wrap the precious & fragile commodity, shake-proof and anti-pressure.

 

USAGE INSTRUCTIONS:

1. Shake the aerosol can for at least 40 seconds.

2. Clean and moisten surfaces with a water sprayer prior to application.

3. Fit the gun or straw on the adaptor. Firmly screw the can on the adapter and turn the flow adjustment screw.

4. Fill the holes and cavities approximately 50% as the foam will expand. Bottom up during application.
