① Pure solvent-free, eco-friendly formulation, safe and compliant.

No solvents are added throughout the entire process, and there are zero VOCs emitted. The product has no irritating odor and fully complies with China’s new national standard GB 36246-2018 for safety of school sports grounds. It is environmentally friendly and suitable for constructing various types of public sports venues.

② Ultra-high viscosity, dense molding, and strong overall integrity

8000-10000The mPa·s ultra-high viscosity property delivers excellent particle suspension, ensuring that the mixture neither sags nor leaks adhesive. The resulting surface boasts high compactness and excellent overall integrity, effectively enhancing the site’s resistance to compression and impact.

③ High-intensity physical performance, with a stable and durable site.

The tensile strength reaches as high as 0.58 MPa, offering excellent structural load-bearing capacity. After curing, it exhibits outstanding shape retention and is resistant to deformation, making it well-suited for frequent stepping and heavy pressure. The surface remains stable and durable, resisting loosening and damage, thus extending its service life.

④ Super strong adhesion, eliminating delamination and layering.

It exhibits extremely strong adhesion to cement, asphalt surfaces, EPDM colored granules, and black rubber granules. The bonding layer adheres tightly and seamlessly, thoroughly resolving common issues such as particle shedding, blistering, and delamination on the site, ensuring a stable site structure.

⑤ Convenient construction, suitable for operations in multiple scenarios.

The formulation is stable and the mix ratio is simple, eliminating the need for complex mixing processes. It can be applied using both manual spreading and mechanical mixing, making it suitable for constructing dense-type and conventional EPDM surfaces and running tracks. The construction process features a high margin of error tolerance.

⑥ High engineering cost-effectiveness

Solvent-free, high-end quality—meeting the industry’s top-grade adhesive performance standards. With moderate procurement costs, solid materials, and low waste, it’s the cost-effective, premium choice for high-quality, highly dense sports surfaces.

The product has poor resistance to yellowing and is prone to yellowing and discoloration when exposed to intense outdoor sunlight over a long period. It is not recommended for use in high-aesthetic surface applications and is better suited for sublayers of sites or outdoor areas where appearance requirements are not particularly high.

1. Construction of various EPDM rubber surface and base layers for sports fields

2. Construction of compacted plastic sports surfaces with high compressive strength requirements

3. Construction of a breathable, high-strength elastic base layer for plastic running tracks

4. Construction and renovation of conventional wear-resistant surfaces for communities, parks, and sports venues.

5. Standard engineering projects with high requirements for site compaction and structural strength

① Standard campus running track subgrade works

Many primary and secondary schools across various regions have adopted this product in bulk for their standard breathable track projects. Its high-viscosity properties ensure that the rubber granules are bonded more tightly, resulting in a compact surface with excellent compression resistance. The track maintains its integrity over the long term without any issues such as loosening or particle shedding, and has successfully passed engineering acceptance on the first attempt.

② Large-scale sports venue and facility projects

Specifically designed for the construction of durable sports venues, this product leverages its high-strength adhesive properties to perfectly suit high-frequency athletic environments. The venue boasts a stable structure, exceptional wear resistance and durability, and extremely low maintenance costs—earning widespread recognition from project contractors.

③ Foreign trade bulk infrastructure site projects

We offer large-scale exports of basic sports field projects to Southeast Asia and the Middle East, with complete solvent-free and eco-friendly certifications. Our structures feature optimal strength tailored to meet the needs of various outdoor sports fields, offering exceptional value for money and ensuring long-term, stable repeat business.

Q1: What’s the difference between premium glue and the regular glues 06 and 20?

A: The core difference isUltra-high viscosity and high-strength styling effectThis product has a viscosity far higher than that of ordinary glue, resulting in better particle adhesion, denser site compaction, and superior structural strength. It is specifically designed for high-strength, highly stable site construction. While ordinary glue emphasizes fluidity, this product focuses on forming hardness and overall integrity.

Q2: Will high viscosity make construction difficult and cause uneven mixing?

A: No. This product features an engineered, optimized formulation that’s perfectly matched to professional track-mixing equipment. It mixes smoothly at room temperature with even particle coating. Simply avoid using it in low-temperature conditions; under normal operating conditions, its construction efficiency remains stable, and the finished result far surpasses that of ordinary adhesives.

Q3: Can this glue be used for flooring?

A: It can be used for ordinary ground surfaces, but due to its poor yellowing resistance, it tends to turn yellow when exposed to prolonged sunlight.More recommended for the base layer and elastic layer of the playing surface.; For high-appearance, premium surface layers, we recommend using yellowing-resistant adhesive.

Q4: Is this an environmentally friendly glue, and can it be used in campus construction projects?

A: This is a pure, solvent-free, eco-friendly adhesive that contains no VOCs or harmful substances. It fully complies with the new national standards for construction of school playgrounds and sports facilities, and has undergone comprehensive environmental testing. You can use it with confidence in schools, kindergartens, and public fitness areas.

Q5: How do I choose between 20 kg and 200 kg packaging?

A: For small repairs, sporadic renovations, and small-area sites, the 20-kg small bucket is recommended—it’s convenient to store and has low wastage. For large standard playgrounds, bulk infrastructure projects, and foreign trade export orders, the 200-kg large bucket is the preferred choice, offering a lower unit price and being ideal for full-container ocean shipping.
