Stretchable Pure Polyurea Membrane – High-Expansion Waterproofing & Coating
The Stretchable Pure Polyurea Membrane is a hot-spray-applied, ultra-flexible waterproofing solution designed for structural elements subject to high expansion and movement. With an elongation capacity of over 600%, this membrane provides exceptional flexibility, seamless adhesion, and superior waterproofing, making it ideal for metal roofs, civil structures, and high-movement surfaces.
Composed of Tecnocoat P-2049-EL/A (isocyanates) and Tecnocoat P-2049-EL/B (amines), this two-component system is applied using specialized spray equipment, forming a fully adhered, joint-free, and watertight protective layer.
Key Features & Benefits
✔ Extreme Flexibility & Stretchability – Elongation >600% at 23ºC / >350% at -40ºC, perfect for expanding and contracting surfaces. ✔ Seamless & Fully Adhered – No joints or overlaps, ensuring complete waterproofing. ✔ High Mechanical Strength – Tensile strength >13 MPa, offering superior impact and wear resistance. ✔ Fast Application & Quick Curing – Tack-free in ±20 seconds, ensuring efficient installation. ✔ Temperature & Weather Resistant – Ideal for structures exposed to extreme environmental conditions.
Ideal Applications
Metal Roof Waterproofing (Zinc, Copper, and Other Expanding Metal Roofs)
Flat or Sloped Asbestos Roof Rehabilitation (Used with TECNOFOAM SPF System)
Protective Coating for Spray Polyurethane Foam (SPF – TECNOFOAM System)
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.
