Non-Curing Rubber Asphalt Waterproof Coating
This product is a paste-like waterproof material made from high-quality petroleum asphalt, rubber, tackifying resin, and special additives through a special process. It has a non-curing property, always maintaining a viscous paste form, with excellent self-healing, adhesion, and creep performance, effectively addressing waterproof layer failure caused by substrate cracking.
Product Features
| Title | Content |
|---|---|
| Non-Curing | Remains in a viscous paste state for a long time, does not harden or crack. |
| Self-Healing | Even if punctured after application, it can self-heal without affecting waterproof performance. |
| Strong Adhesion | Permanently bonds with the substrate, no water migration or peeling. |
| Aging Resistance | Excellent weather and corrosion resistance, long service life. |
| Easy Application | Can be applied by trowel or spray, suitable for complex substrates. |
