Features & Benefits
1. Strong weather resistance, anti-ultraviolet, anti-oxidation, high and low temperature resistance(-30℃ to +60℃), and not easy to age and fade.
2. The bonding force is high, and the bonding between the bottom layer, surface layer and particles is strong, meeting the requirements of professional competitions for track smoothness.
3. The elastic modulus is moderate, which can effectively absorb the impact of sports and reduce the risk of injury to athletes.
4. The wear resistance rate is generally less than 2.5%, and the service life can reach 15-20 years; it has strong resistance to compression and running shoe spikes.
5. Most products use solvent-free or low-volatile organic solvent formulas, which are environmentally friendly.
6. The bottom glue and particles form a porous structure, which can quickly drain away rainwater and prevent bubbling.
7. Bright color, good color retention, keep bright for a long time.
Applications
1. Adhesion of plastic runways, fully plastic runways, and hybrid runways in sports venues, school playgrounds, kindergartens, various track and field fields, basketball courts, football fields, fitness paths, and national fitness parks.
2. For large hardened surfaces such as airport runways, aprons, taxiways, and around terminal buildings, special polyurethane caulking glue or caulking glue is often used for overall bonding and crack repair.
3. For traffic markings on asphalt or concrete roads, airport runway markings, etc. use two-component polyurethane marking glue.
4. Paving of playgrounds, golf courses, and community sports facilities.

construction method
1. Base surface treatment
Clean, dust and dry, compact and smooth the concrete base surface, and apply primer or asphalt surface layer if necessary.
2. Primer (bottom layer) construction
Single component polyurethane is used, and the ratio is usually glue: particles≈1:7. Mechanical paving or manual paving, scraping and compacting, with a thickness of about 3-5mm, initial solidification for 3 hours at room temperature, and construction can continue the next day.
3. Surface glue (surface layer) construction
Use polyurethane surface glue and spray or roll coating with EPDM/PU particles, usually two or three times to form a non-slip texture. The thickness of the surface layer is about 10-12mm, and the thickness of the overall track is about 13-15mm. After curing, the surface is smooth and drains smoothly.
4. Seams and caulking
Use special caulking glue or sealing glue to seal the joints between the bottom layer and the surface layer to prevent glue leakage.
5. Underline Use two-component polyurethane marking glue to mark lines according to IAAF standards.
