Feviseal PU Foam Spray- 750ml

Feviseal PU Foam Spray is a one-component, CFC-free polyurethane foam sealant designed for sealing, insulating, and filling joints, cracks, and holes in construction and other applications. 

Key features

• Packaging: Typically available in 750 ml cans/bottles.
• Application: A straw applicator is usually included for easy use.
• Curing: It's a moisture-curing foam, meaning it hardens by reacting with moisture in the air.
• Insulation: It provides excellent thermal and acoustic insulation.
• Adhesion: It adheres well to most common building materials like concrete, brick, wood, and metal, generally without the need for a primer.
• Workability: Once cured (typically 60 minutes), the foam can be cut, sanded, and painted.
• Expansion: The foam expands to fill gaps, taking on 2 to 3 times its original volume, depending on temperature and humidity.
• Dimensional Stability: It exhibits good dimensional stability after curing.
• Flammability Class: It holds a B3 flammability rating.
• Application Temperature: It can be applied in temperatures ranging from +5°C to +40°C.
• Tack-free Time: It becomes tack-free in approximately 10 ± 2 minutes at 20°C and 45% relative humidity.
• Yield: One 750 ml can can yield up to 45 liters in free expansion and 25 to 30 liters when applied in joints.

Common applications

• Sealing joints and cracks:
  • Between partition walls and ceilings.
  • Around wooden door frames and walls.
  • In structural spaces between prefabricated elements.
  • Around chimneys, roof protection, roof panels, and wall panels.
  • Around cables and pipes passing through walls and ceilings.
• Insulating: It can be used for heat and sound insulation in various areas.
• Filling: It's ideal for filling gaps and cavities.

Important notes

• Moistening the surface: Dampening the surfaces before application is recommended, especially in dry environments, to facilitate curing and promote better adhesion and cell structure. However, avoid leaving standing water droplets.
• Don't overfill: Fill the gaps only to about 30-50% to allow for expansion.
• Shake well: Shake the can vigorously before and during use to ensure a homogeneous mix and optimal foaming.
• Inverted use: For best results, hold the can upside down during application.
• Protect from UV: The cured foam is not UV resistant and should be painted or covered if exposed to direct sunlight.
• Safety Precautions: Always wear gloves and eye protection when handling the product.
• Disposal: Dispose of the can and residual materials at an authorized waste disposal site.

In summary, Feviseal PU Foam Spray is a versatile and effective solution for a wide range of sealing, insulating, and filling tasks in construction and related industries.
