X-3705 Manual Applied Polyurea Waterproof Coating
Product Info
X-3705 redefines manual polyurea application with its solvent-free, odorless formulation designed for complex waterproofing projects. This two-component, high-elasticity coating cures into a seamless membrane with exceptional UV stability and hydrolysis resistance. Engineered for roller/scraper application, it delivers sag-resistant builds up to 1mm per pass – ideal for vertical surfaces, foam substrates, and critical water containment structures.
Key Features
✅ Revolutionary Application Simplicity
- Roller/scraper application – no spray equipment needed
- 30-40 minute pot life (25°C/50% RH) enables precision work
- Self-leveling for pin-hole free finishes
✅ Extreme Performance Elasticity
- >700% elongation at break | 45N/mm tear strength
- Temperature endurance: -60°C to 80°C
- Water absorption: <3% (7-day immersion)
✅ Eco-Safe Formulation
- 100% solids | Zero VOC | Solvent-free
- Compliant with global environmental regulations
✅ Substrate Versatility
- Bonds to foam, concrete, tile & mortar without sagging
- Primer options available for challenging surfaces
The X-3705 polyurea coating is ideal for:
• Foam Surface Protection: Pool floats, insulation layers
• Water Containment: Swimming pools & water parks, Fountain linings & decorative water features
• Architectural Waterproofing: Roof membranes, Bathroom/kitchen wet areas, Underground structures
• Concrete Protection: Parking decks, balconies
