Product Introduction
JY-NCR Non-Curing (Non-Solidify) Rubber Asphalt Waterproof Coating is an innovative waterproofing material newly developed and produced by our company, standing out as a high-performance waterproof coating designed to redefine reliability in moisture protection. This single-component waterproof coating is formulated with rubber powder, high-molecular polymers, and asphalt as core ingredients, enhanced by specialized modifiers and additives to deliver exceptional performance.
A key advantage of this non-curing rubber asphalt waterproof coating is its unique ability to remain non-solidified even after long-term exposure to air, ensuring it maintains a flexible, viscous state. It is insoluble in water and boasts superior bonding strength, making it highly adaptable to complex construction surfaces—ideal for navigating irregular or uneven substrates where traditional waterproof coatings may struggle. What truly sets it apart is its self-healing capability: it can automatically seek out and seal leak points, repairing damaged waterproof layers to provide permanent, uninterrupted waterproofing protection.
Committed to safety and sustainability, this waterproof coating is solvent-free, fully meeting national safety and environmental protection standards. It also exhibits outstanding creep properties, coupled with excellent waterproof performance and aging resistance, ensuring long-term durability in diverse environments. Versatile in application, it supports multiple construction methods such as brushing, spraying, and grouting for leak plugging. For enhanced protection, it can be combined with waterproofing membranes to form a composite waterproof layer; alternatively, it can function independently as a standalone waterproof layer, with a separator layer recommended on its surface.
Whether for new construction or renovation projects, JY-NCR Non-Curing Rubber Asphalt Waterproof Coating delivers a robust, adaptable, and eco-friendly solution, solidifying its position as a top-tier choice among modern waterproof coatings.

As a high-performance waterproof coating, JY-NCR Non-Curing (Non-Solidify) Rubber Asphalt Waterproof Coating integrates multiple outstanding properties, making it a reliable choice for various waterproofing projects. Its core performance features are detailed as follows:
This non-curing rubber asphalt waterproof coating excels in adapting to structural deformations. When the substrate cracks or stretches the waterproof layer, the non-curing rubber asphalt waterproof layer absorbs the stress and seals the micro-cracks of the substrate. This unique advantage ensures the long-term integrity of the entire waterproof system, avoiding waterproof failure caused by substrate changes that often troubles traditional waterproof coatings.
A key highlight of this waterproof coating lies in its prominent self-healing ability. If the waterproof layer is punctured by external forces, the damage point will not expand, and there will be no water channeling at the bottom of the waterproof layer. Moreover, the creep property of the material can self-heal minor leakage issues, greatly improving the reliability of the waterproof layer. This not only reduces the frequency of post-construction maintenance but also lowers the overall engineering maintenance cost, outperforming many conventional waterproof coatings in long-term usability.
JY-NCR Non-Curing Rubber Asphalt Waterproof Coating maintains stable performance in harsh environments. It has excellent aging resistance, which prevents the waterproof coating from deteriorating due to long-term exposure to sunlight, rain, and other factors. Meanwhile, its excellent low-temperature flexibility ensures that the waterproof layer does not crack or become brittle in cold weather. Additionally, the coating exhibits strong corrosion resistance, effectively withstanding erosion from chemical substances in the environment and extending the service life of the waterproof system.
This waterproof coating boasts strong adhesion, capable of bonding firmly with different types of substrates such as concrete, metal, and masonry. Even on damp substrates, it can still form a tight bond without peeling off easily. This feature eliminates the need for complex substrate pretreatment in many cases, simplifying the construction process and ensuring the stability of the waterproof layer.
With a solid content of over 99%, this non-curing rubber asphalt waterproof coating supports continuous construction through material feeding and pumping. It can be applied in one coat to reach the specified thickness, with a construction speed of up to 115 m²/h. This high-efficiency construction performance not only shortens the project cycle but also reduces labor costs, making it suitable for large-scale waterproofing projects.
As an eco-friendly waterproof coating, it is non-toxic and solvent-free, and no open flame is required during construction. This not only ensures the safety of construction workers but also avoids environmental pollution caused by solvent volatilization, fully complying with national safety and environmental protection standards for waterproof coatings.
Application Scope
JY-NCR Non-Curing (Non-Solidify) Rubber Asphalt Waterproof Coating is a versatile waterproof coating engineered to excel in diverse and challenging environments, making it a go-to solution for projects requiring reliable, adaptable moisture protection.
This high-performance waterproof coating is particularly suited for substrates with significant undulations, high stress, and areas prone to predictable or frequent deformation—where traditional waterproof coatings may fail due to rigidity. Its unique non-solidifying property allows it to flex and adjust with surface movements, ensuring long-term integrity in dynamic conditions.
It is also an ideal choice for projects where open-flame construction, mechanical application, or cold-adhesive-based waterproofing methods are restricted or prohibited. This makes it a safe and practical alternative in sensitive environments where safety regulations or site constraints limit conventional waterproof coating techniques.
Beyond these specialized scenarios, JY-NCR Non-Curing Rubber Asphalt Waterproof Coating delivers exceptional results in a wide range of standard waterproofing projects, including concrete and color steel roofs, underground structures, water tanks, and tunnels. Whether for new construction or waterproofing renovations, it provides consistent, durable protection, solidifying its role as a trusted waterproof coating across residential, commercial, and industrial applications.
Construction Plan for Non-Curing Rubber Asphalt Waterproof Coating and SBS Waterproof Roll Composite Waterproof System
Heating and Melting:Pour the non-curing rubber asphalt waterproof coating into a dedicated heating tank, heat to 180-200℃, and stir thoroughly until no particles remain—ensuring the asphalt waterproof coating achieves a uniform, workable consistency.
Coating Application Methods:
- Spraying: Use specialized spraying equipment to apply the asphalt waterproof coating in one pass, achieving a thickness of 1.5-2mm (one-time film formation).
- Scraping: Apply the non-curing rubber asphalt waterproof coating in layers using a toothed scraper, with each layer at 1mm thickness and a total thickness of ≥2mm.
Detail Processing:Pre-coat corners, pipe roots, and other vulnerable areas with a 1mm thick layer of the asphalt waterproof coating, then embed a non-woven reinforcement layer for enhanced durability.
Laying Timing:Install the SBS roll immediately before the non-curing rubber asphalt waterproof coating cools—this ensures optimal hot-melt bonding between the roll and the asphalt waterproof coating.
Hot-Melt Construction Method:After positioning the roll, heat the bottom surface of the roll and the underlying asphalt waterproof coating with a flame gun. Once the asphalt melts, roll and press the roll firmly to ensure full adhesion.
Overlap Requirements:Long-side overlaps must be ≥100mm; short-side overlaps ≥150mm. Seal all overlaps by hot-melting with a spray gun, integrating them tightly with the asphalt waterproof coating.
Optional Cold Bonding Method:For specific scenarios, apply the SBS roll directly onto the uncured asphalt waterproof coating, then roll to eliminate air bubbles and ensure secure bonding.
- Bonding Strength Check: Tear testing should show no detachment between the SBS roll and the non-curing rubber asphalt waterproof coating; no hollowing is allowed between layers.
- Thickness Detection: Use a needle puncture method to verify the total thickness of the asphalt waterproof coating and SBS roll composite system is ≥4mm.
