Single Component Polyurethane Sealant
The product is a single component polyurethane sealant that activates on contact with water, supplied by Tengpeng Waterstop Co., Ltd in China. It is a gun‑grade formulation that expands up to 600% of its original volume, adheres to steel, HDPE, PVC and damp surfaces, and provides a service life of 15 to 20 years. The sealant resists hydrochloric acid, salt water, sodium carbonate and potassium hydroxide, and is certified as non‑toxic for drinking‑water applications.
In the broader market, similar hydrophilic polyurethane sealants typically expand between 300% and 500% and achieve a Shore A hardness of 70 ± 5 after curing. Standard cure times are a skin formation within 2‑4 hours and full strength in 24‑48 hours, while temperature flexibility usually covers - 30 °C to 80 °C. Industry standards such as ISO 11600 classify the product under Class A sealants, and packaging is commonly offered in 25 kg cartridges or bulk drums.
The sealant is used for waterproofing joints in tunnels, subways, underground parking structures, basements and foundation walls, as well as for water‑stop applications in plumbing and sewer lines. Contractors, infrastructure developers and importers source it for its reliable expansion and chemical resistance. Buyers should confirm minimum order quantities, preferred Incoterms and payment terms directly with the supplier before placing an order.
