POLYURETHANE-BITUMEN RESIN

Soprema ALSAN FLASHING is a ready-to-use, single-component, waterproof polyurethane-bitumen resin resistant to UV radiation. Designed for creating seamless connections on bituminous insulation and joining various surfaces to ensure continuous waterproofing. Applicable on substrates such as modified bitumen membranes (SBS, APP), metal, wood, concrete, and rigid PVC.

Features of Soprema ALSAN FLASHING:

• Innovative SOPREMA solution: Combines bitumen and polyurethane for exceptional durability and flexibility.
• Certified quality: European technical approval and CE marking ensure reliability and safety.
• Ease of application: Quick and straightforward, saving time and effort.
• Minimal thickness (1.2 mm): Compact solution that requires no sheet metal work.
• Excellent adhesion: Bonds well to various surfaces and resists weather conditions and UV exposure.
• No primer or torch required: Simplifies application, making it safer and more efficient.
• Versatile compatibility: Suitable for SBS and APP modified bitumen membranes, plaster, concrete, metals (steel, aluminum, lead, and zinc), and plastics like polyester and rigid PVC.
• Aging and temperature resistance: Withstands extreme cold (-36°C) and remains durable over time.
• Flexibility (500%): Prevents cracking or deformation under temperature changes or surface movements.
• Special variant – ALSAN FLASHING JARDIN: Certified by the German Landscape Research Institute (FLL) for anti-corrosion properties, specifically for green roof applications.

Advantages:

• High-quality, reliable performance.
• Easy, fast application saves time and labor.
