Product Description




1. Property :


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.

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

  1. Fill the joint between concrete and door, window
  2. Fill the joint between two walls
  3. Fill the joint among door , window ,doorpost and suspended rolling door
  4. Fill the joint between wall and floor as well as electrical wire and wall
  5. Fill the gap among prefabricated parts
  6. Fill the joint between rooftop and ceiling , between rooftop and wall , as well as rooftop and attic
  7. 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;

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


5. Features:

  1. 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
  2. Environmental temperature wide-range application for use: the highest degree is 400C and the lowest degree is 00C , the products can work normally
  3. Measuring conveniently: the volume of the foam can controlled freely , the minimum can reach to 1 ml so it is helpful to small repairings
  4. Automatic expand: owing to the expanding volume can reach to 50-70 times after jet the foam so it can filling every corner sonly
  5. 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
  6. Automatic adhesion : needless processing of the surface having good adhesion between the most of base materials , particularly the wet surface.
  7. Small pressure of foaming :the volume of foam can expanding 20%-30% during it cure, so no damage to the base materials
  8. Wide application: widely applied to the building and Industry field and so on .

6. 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.
