One component expanding PU Foam is a multi-purpose polyurethane foam that may be used for a wide range of building applications, such as filling gaps around pipes, draft proofing and sealing window and door frames, bonding wood and brick and sealing cracks and crevices. Adhesion is good to most construction surfaces, such as wood, brick, concrete, metals and many plastics. When cured it is weather and rot proof and can be trimmed, sawn,
sanded and, if necessary, painted and plastered. PU foam will cure when moisture in the air reacts with the
chemicals of the foam. All one-component foams meet GB8624-97 flame resistance requirements for caulks and sealants. We occupy 60-70% of the domestic market and are one of the largest suppliers in Asia.

PU Foam Applications-------
1. Door and window installation: Seal, fill, fix and adhere the gap between doors, windows and walls; Fixing and insulating of door and window frames
Fill the joint between concrete and door, window
Fill the joint between two walls
Fill the joint among door , window ,doorpost and suspended rolling door
Fill the joint between wall and floor as well as electrical wire and wall
Fill the gap among prefabricated parts
Fill the joint between rooftop and ceiling , between rooftop and wall , as well as rooftop and attic
Insulating electrical outlets and water pipes.
2. Advertisement model: Make model and sand plate, repair show board; 3. Sound insulation and absorption: Insulate and absorb sound as sealant in speech room and broadcast studio; 4. Gardening: Make ikebana and gardening simple and beautiful; 5. Daily maintenance: Repair the hole, gap, brick and floor; 6. Resisting water and fixing leak: Mend the hole of water pipe and cloaca; 7. Packing and transportation: Pack valuable and fragile goods easily and quickly, resist shock and press
Carrying and using conveniently: the raw material jet promptly and formed when open the valve of the can lightly needless the foaming machine and the external power
Environmental temperature wide-range application for use: the highest degree is 400C and the lowest degree is 00C , the products can work normally
Measuring conveniently: the volume of the foam can controlled freely , the minimum can reach to 1 ml so it is helpful to small repairings
Automatic expand: owing to the expanding volume can reach to 50-70 times after jet the foam so it can filling every corner sonly
Humidity cure: the foam are reacting with the air or the moisture of the building materials promptly when jet so it is unnecessary to add the curing agent or others
Automatic adhesion : needless processing of the surface having good adhesion between the most of base materials , particularly the wet surface.
Small pressure of foaming :the volume of foam can expanding 20%-30% during it cure, so no damage to the base materials
Wide application: widely applied to the building and Industry field and so on .
Guide for use------------
It can be applied to damp surfaces. OCF is moisture curing. The more moisture, the quicker the cure. It must be protected from Uvin external application to prevent discoloration and deterioration of the foam. Conventional paints can be applied to the foam. In overhead applications, foam must be retained in place to prevent its falling away until adhesion grips. It can be used in temperature range of 5-40oC, if in low temperature condition, we suggest that it should be placed in 25-30oC circumstance for 30 minutes to ensure the better performance. Uncured foam can be removed with solvent. But after cure, foam can only be removed mechanically (sanded or scraped off). Uncured foam sticks to hands and clothing.
Should be stored and transported in vertical position.
Should be kept at room temperature for at least 12 hours before the application.
Use before see bottom of the can.
Harmful by inhalation , irritating to eyes, respiratory system and skin.
Do not breathe spray vapour . wear suitable protective clothing and gloves
Use only in well – ventilated areas.
