Description

Soudaflex 40FC is a one-component, moisture-curing polyurethane sealant and adhesive that combines high mechanical strength with long-lasting elasticity. It adheres strongly to most common building materials — including concrete, stone, metal, wood, and many plastics — without the need for a primer in most cases.

Once cured, it forms a permanent, flexible seal that accommodates movement and vibration, making it particularly well-suited to floor joints, industrial sealing, and construction bonding applications. It also provides excellent chemical and weather resistance, ensuring reliable performance in both interior and exterior conditions.

Key Features & Benefits

  • High-modulus polyurethane formulation for strength and flexibility
  • Excellent adhesion to most substrates without primer
  • Fast-curing and easy to apply
  • Remains permanently elastic after curing
  • Chemical- and weather-resistant for long-term durability
  • Paintable with most common paints (after full curing)
  • Ideal for structural bonding and floor joints

Applications

  • Sealing and bonding in construction and manufacturing industries
  • Concrete flooring joints and movement joints
  • Structural bonding on materials subject to vibration or dynamic stress
  • Suitable for both interior and exterior use
