The product is a moisture curing polyurethane prepolymer formulated as a single‑component sealant for road, highway and bridge deck joint filling. According to the supplier data it appears as a gray, homogeneous paste (product item PU820) with a density of 1.35 ± 0.1 g/m³, solid content of 98 %, surface dry time of up to 4 hours, tack‑free time between 6 and 16 hours and full cure in 24 hours; flow ability is described as self‑leveling. The sealant offers excellent resistance to water, oil, acid, alkali and puncture, making it suitable for concrete and asphalt substrates without the need for mixing.
The formulation belongs to the broader class of moisture‑curing polyurethane sealants that typically exhibit tensile strength around 1.5 MPa, elongation at break near 300 %, and Shore A hardness of about 70. Standard industry practice limits service temperature to - 30 °C … 80 °C and expects a storage life of roughly 12 months when kept in sealed containers. Typical packaging for comparable products is a 25 kg drum, and many manufacturers certify compliance with ASTM C920 for joint construction sealants.
Primary users are infrastructure contractors, bridge engineers and road‑building firms that require long‑lasting joint protection. The supplier is based in Suzhou, Jiangsu, China and holds a harbor‑level verification tier; however the response rate shown is 0.00, so buyers should request a current business licence and product data sheet before committing. Trade terms such as MOQ, FOB point and payment method are not disclosed in the listing and must be confirmed directly with the supplier.

Before placing an order, verify the supplier’s business licence, product data sheet and any available test reports. The harbour verification tier confirms basic registration, but the zero response rate suggests you should request recent references or a factory audit to ensure reliability. Also confirm that the sealant complies with any local construction standards required for your project.
Discuss logistics early: ask whether the supplier ships FOB Shanghai, the expected lead time for a first batch, and the Incoterms they are comfortable with. Payment methods such as a confirmed Letter of Credit at sight are common for bulk construction chemicals, but the exact terms should be agreed in writing before production begins.
Arrange for quality assurance by requesting a third‑party inspection at the loading port, a certificate of conformity to the relevant standard (e.g., ASTM C920), and a retention sample of the cured sealant. Documentation should include a Material Safety Data Sheet, a test report for tensile strength and elongation, and a certificate of origin. These steps help minimise risk and ensure the product meets the performance criteria of your infrastructure project.
