Elongable Polyurea Membrane – High-Flexibility Waterproofing & Coating
The Elongable Polyurea Membrane is a highly stretchable, hot-spray-applied polyurea solution designed for waterproofing, protection, and sealing. Engineered for structural movement applications, it provides seamless adhesion, superior flexibility, and high mechanical resistance, making it ideal for industrial, commercial, and construction projects.
This system consists of Tecnocoat P-2049/A (isocyanates) and Tecnocoat H-2049-EL/B (resins), which react to form a solid, waterproof, and stretchable polyurea membrane.
Key Features & Benefits
✔ Highly Flexible & Stretchable – Elongation at break >450%, ideal for structural movement applications.
✔ Seamless & Watertight – No joints or overlaps, ensuring a fully adhered waterproofing layer.
✔ Fast Application & Curing – Tack-free in ±15 seconds, allowing for rapid project completion.
✔ High Mechanical Strength – Tensile strength >20 MPa, offering excellent durability.
✔ Versatile & Multi-Surface Compatibility – Suitable for metal, concrete, polyurethane foam, and composite materials.
Ideal Applications
- Metal Roof Waterproofing (zinc, copper, etc.)
- Civil Engineering Structures (bridges, beams, retaining walls, concrete decks)
- Sloped & Flat Roofs (IRMA systems, balconies, overhangs, and walkways)
- Concrete Foundation & Retaining Wall Protection
- Vehicle & Boat Coatings (bed liners, marine protection)
- Furniture & Thematic Design Elements
- Asbestos Roof Rehabilitation (used with TECNOFOAM)
- Protective Coating for Spray Polyurethane Foam (SPF)
Application Method
This hot spray-applied polyurea requires specialized spray equipment for uniform application. A minimum thickness of 1.5mm is recommended for optimal performance.
