Spray-applied polyurea is a high-performance elastomer material formed by the reaction of isocyanate components and amino compounds. Relying on high-temperature and high-pressure spray technology, it can instantly cure on any substrate (such as concrete, metal, wood) to form a seamless, high-strength, and highly elastic waterproof protective layer. This unique curing property gives it significant advantages in the waterproofing field.
Rapid Curing: Surface-dry in 5-30 seconds, walkable in 1 minute—no long waiting time. The construction period is 70% shorter than traditional methods, greatly improving efficiency.
Impact & Wear Resistance: Tensile strength ≥16MPa, tear strength ≥50kN/m. It can resist mechanical damage and vehicle rolling, significantly extending the protective layer's service life.
Seamless Protection: 100% integral film formation, no seam risks. It fundamentally eliminates water channeling, ensuring longer-lasting and reliable waterproofing.
Superior Weather Resistance: Stable performance at -40°C to 150°C. UV-resistant, salt spray-resistant, and non-chalking, adapting to extreme cold, heat, and harsh outdoor environments.
Eco-Friendly: 100% solid content, zero VOCs. Certified for drinking water contact (e.g., NSF-61), making it suitable for scenarios with high environmental requirements.
Infrastructure Projects: Provides durable protection for concrete structures of core infrastructure (tunnels, bridges, high-speed railways), ensuring structural safety and service life.
Industrial Protection: Integrates anti-corrosion and waterproofing for industrial scenarios (sewage treatment tanks, chemical workshops), resisting chemical erosion and water penetration.
Residential Buildings: Applied to roofs, exterior walls, color steel tiles, sky gardens, etc., to provide long-term waterproofing and enhance living environment safety and comfort.
Specialized Fields: In water parks, swimming pools, offshore platforms, its anti-seepage and anti-corrosion properties ensure normal operation and user safety.
