NRAC Non-Curing Waterproof Coating is a high-performance rubberized asphalt-based sealant designed for demanding waterproofing environments. Its non-curing formulation ensures permanent elasticity, allowing it to adapt to substrate movements, temperature fluctuations, and minor structural shifts--without cracking or peeling.
Engineered for large-scale waterproofing applications such as tunnels, bridges, rooftops, basements, and subways, this product delivers consistent sealing performance, even under extreme weather or heavy load.
Unlike conventional waterproof materials that harden over time, NRAC Non-Curing Coating remains flexible and viscous, allowing it to:
| Feature | Description |
|---|---|
| Non-Curing & Flexible | Remains in a semi-solid state, never fully hardens |
| High Bond Strength | Strong adhesion to concrete, stone, wood, steel, and other substrates |
| Excellent Creep Resistance | Resists deformation under long-term loading |
| Self-Healing Ability | Automatically repairs microcracks or voids caused by structural movement |
| Anti-Corrosion & Anti-Aging | UV resistant and stable in both low & high temperatures |
| Environmental Safety | Low VOC, solvent-free, non-toxic and eco-friendly |
| Easy to Apply | Cold-applied by brush, roller, or spraying - no heating required |
Ideal for both new construction and renovation projects in the following areas:

Surface Preparation: Ensure substrate is clean, dry, and dust-free. Remove any oil, grease, or loose material.
Application Method: Brush, roller, or airless spray. Can also be used with fiberglass reinforcement layer.
Thickness: Recommended wet film thickness is 1.5-3mm. Apply in layers if needed.
Curing Time: Surface dry in 4-6 hours. Final setting in 24-48 hours (depends on environment).
Precautions:
We offer customized product packaging, label design, and bulk orders. Our factory supports OEM/ODM production to suit your branding and market requirements.
Yes. The coating is designed to perform in extreme temperatures from -25°C to +80°C and is UV-stable.
Absolutely. Its non-curing nature ensures long-term waterproof performance even in submerged or high-humidity areas.
No. This is a cold-applied material. No heating or melting is needed.
Unlike solidifying coatings, this product remains permanently flexible and does not crack or age easily, making it ideal for structures prone to movement or vibration.
