PRODUCT DESCRIPTION

Superior Expansion PU Foam H55 is a one-component, ready to use multi-purpose polyurethane foam. It is fitted with a plastic adaptor 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. Higher expansion rather then normal PU Foam.

 

APPLICATIONS AREAS

Installing, fixing and insulating of door and window frames.

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

Connecting of insulation materials and roof construction.

Bonding and mounting.

Insulating the electrical outlets and water pipes.

Heat preservation, cold and sound insulation.

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

 

PRODUCT FEATURES

Excellent adhesion to a wide variety of surfaces such as UPVC, masonry, brick, block work, glass, steel, aluminum, timber and other substrates (except PP, PE and Teflon).

High thermal and asoustical insulation.

Very good filling capacities

High Bonding strength with B2 fire Fire class in DIN4102 part 2

Application temperature between +5 and +35

Optimal application temperature between +18 and +25

Environmentally friendly. It contains CFC-free propellants which are harmless to the ozone layer.

 

APPLICATIONS:

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

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.

5. Foam will be tack-free in about 10 minutes.

6. Excess can be trimmed in about 20 minutes.

 

STOREAGE & SHLF LIFE

12 months in unopened packing store in temperature between +5 and +25. Keep in cool, shade and well ventilated area. Always keep the can with the valve pointed upwards
