POLYUREA RAYSTON is a cutting-edge waterproofing technology developed by KRYPTON CHEMICAL SL, a leading Spanish manufacturer. This pure polyurea membrane is designed for spray-applied waterproofing, offering unmatched flexibility, durability, and rapid curing. Ideal for industrial and construction applications, POLYUREA RAYSTON combines advanced chemistry with ease of use, making it a top choice for engineers and contractors worldwide. In this article, we explore its key properties, applications, and competitive advantages that position it as a leader in modern waterproofing solutions.

Unique Properties of POLYUREA RAYSTON

 

1. High Flexibility and Crack Bridging:
   With an elongation rate of 324%, POLYUREA RAYSTON adapts seamlessly to structural movements and thermal expansion without cracking.
   • Tensile Strength: 16.2 MPa ensures long-term durability.
   • Tear Resistance: 69 N/mm (ISO 34-1, Method B).
2. Resistance to Extreme Conditions:
   • Temperature Range: Stable up to 200°C for 6 hours and remains flexible at -45°C without cracking (UNE_EN 495-2001).
   • Chemical Resistance: Excellent performance against hydrochloric acid, sodium hypochlorite, petroleum, oils, and sulfamic acid.
   • UV Resistance: While slight color fading may occur under sunlight, mechanical properties remain intact. For aesthetic purposes, an aliphatic topcoat like Impertrans/Colodur can be applied.
3. Rapid Curing:
   • Initial Cure: Touch-dry in 5 minutes at 25°C.
   • Rain Resistance: Achieved within 10 minutes of application.
4. Adhesion Strength:
   • Concrete (with epoxy primer): 4.0 MPa
   • Steel (with PU primer): 5.3 MPa
   • High-Density PU Foam: >1.5 MPa (foam failure).

Competitive Advantages Over Traditional Waterproofing

• Superior Flexibility: Outperforms rigid materials like epoxy and bitumen in dynamic environments.
• Fast Application: Covers 1,000+ m²/day in a single, seamless layer.
• Environmentally Safe: Solvent-free and compliant with EN 1504-2 for drinking water contact.
• Longevity: 20+ years of service life with minimal maintenance.

Professional Application Guidelines

1. Surface Preparation:
   • Ensure surfaces are clean, dry (<4% moisture), and free of dust, oil, or cracks.
   • Mechanically abrade concrete substrates and apply epoxy primers for optimal adhesion.
2. Mixing & Spraying:
   • Preheat components to 68°C (A) and 70°C (B).
   • Apply at 140 bar pressure for a uniform 1.5–2 mm thickness.
3. Maintenance:
   • Regularly remove debris and clean with water/mild detergent.
   • Reapply UV-protective topcoats (e.g., Impertrans) if aesthetics are critical.

Certifications & Compliance

• CE Marking: Compliant with EN 1504-2 (Class II water permeability: 0.9 g/m²·day).
• Fire Safety: Rated B roof t1 (EN 13501-5:2005+A1:2010).
• Abrasion Resistance: 10 mg loss (Taber test, 1,000 cycles).
