Spraying Rapid Setting Rubber Asphalt Waterproof Coating is a liquid rubber emulsion (Component A, solid content 55%–75%) formulated from anionic rubber emulsion and specially formulated nanoscale asphalt emulsion. When reacted with a special curing agent (Component B), it forms a continuous, dense waterborne polymer coating that provides waterproofing, anti‑corrosion, anti‑seepage, thermal insulation, and sound insulation. Its technical level has been certified by national ministries and commissions as reaching internationally leading standards.

1. True “Skin‑Type” Protection Using mechanical conformal spraying, it perfectly covers various irregular or complex substrates. The bonding strength to concrete substrates is ≥0.6 MPa, forming a continuous, dense, joint‑free “skin‑type” protective layer. This effectively solves the water‑channeling problem caused by lap joints or poor adhesion in traditional materials.

2. Ultra‑High Elongation, Self‑Densifying, Self‑Healing, and Intelligent Repair The average elongation at break exceeds 1000%, and the recovery rate is over 85%. After 2 million cycles of railway fatigue simulation testing, it resists cracking and puncture, and its self‑densifying and self‑healing properties effectively address leakage issues caused by structural stress deformation, settlement, expansion cracking, and penetration.

3. Excellent Anti‑Corrosion and Anti‑Seepage Performance After 2400 hours of immersion in chloride‑salt and sulfate environments, the coating surface shows no blistering, bubbling, delamination, or cracking. In neutral salt‑spray conditions, the material shows no blistering, rusting, cracking, or peeling after 1500 hours, achieving heavy‑duty anti‑corrosion grade performance. The permeability coefficient is 7.8 times 10 to the negative thirteenth power cm/s, making it suitable for anti‑seepage and anti‑corrosion applications in hydraulic engineering, dam structures, and wastewater treatment.

4. Unique Back‑Bonding Performance The peel strength with post‑cast concrete reaches 4.1 N/mm. When applied to basement floor slabs, non‑slope underground structure sidewalls, or mined tunnels, it ensures full adhesion between the waterproofing layer and the structural face exposed to water, guaranteeing reliable waterproofing.

5. Service Temperature Range: –50°C to 160°C

6. Full Life‑Cycle Protection Excellent weather resistance has been verified by the China National Building Materials Testing Center, with accelerated artificial weathering tests lasting up to 10,000 hours. The coating can achieve the same service life as the building structure, providing full life‑cycle protection for the structure.

7. Convenient and Efficient Application Applied by mechanical spraying at ambient temperature, the process emits no toxic or hazardous gases and presents no fire safety hazard. The material sets within 4 seconds after spraying, and a single pass can reach the design thickness. Construction efficiency is 4 to 10 times that of traditional processes.

8. Can Be Applied on Damp Substrates The material naturally allows moisture to escape; construction is possible when the substrate moisture content is below 28% (damp but without standing water). This prevents work stoppages during rainy seasons and overcomes the drawback that traditional waterproofing materials cannot be applied on wet surfaces.

9. Can Be Applied at –15°C in Winter A patented winter‑construction product has been developed, overcoming the technical difficulties of applying waterborne coatings in winter. Normal application is possible at temperatures above –15°C.

10. Full‑Chain Waterborne Environmental Friendliness, Energy Saving, and Carbon Reduction The material contains no organic solvents. VOC, free formaldehyde, benzene, toluene, xylene, and soluble heavy metals are all not detected. It has obtained China’s Three‑Star Green Building Material Certification and meets the safety evaluation standards for drinking water protective materials. According to assessments by the Chinese Academy of Environmental Sciences, compared with similar products, the full life‑cycle carbon emissions can be reduced by up to 86%.
