Water Swelling Polyurethane Sealant Product Description
TP640-220/400 Water Swelling Poyurethane Sealant are a one-component, water-swelling elastomeric sealant. It is based on the prepolymer of polyurethane and contains a special water-swelling unit. Swellable sealant has elastic rubber sealing water and double-sealing sealing mechanism of water expansion and water-stopping after water. It is suitable for waterproofing of concrete construction joints. Anti-leakage of various types of embedded components.

Water Swelling Polyurethane Sealant Special Characteristics
● Water swelling poyurethane sealant has good water-stopping effect: it has the elastic sealing water of rubber and the double sealing water stopping mechanism of its own volume expansion and water stop after water, and can resist water pressure of 2.5Mpa.
● Good expansion: high expansion rate, reaching more than 220% or 400%.
● Water swelling sealant is convenient construction: single component, glue, standard caulking gun can be used.
● Construction tight & close: It can be firmly attached to the concrete surface regardless of whether the base surface is wet, smooth or rough.
● Water expansion sealant is safe and environmentally friendly: safe, non-toxic, water tight sealant for concrete is an environmentally friendly product in contact with drinking water.
● Cost-effective: The performance is better than the traditional construction joint waterproof material, such as steel edge rubber water-stop glue or tape, the price is reasonable.
Water Swelling Polyurethane Sealant Typical Application
●Water stopping sealant can be used for railway tunnels, road tunnels, urban subways, underground structures of buildings, sewage treatment tanks, etc.
●The construction joints of various underground structures are waterproof.
●The underground structure is watered after the pouring.
●Watertight sealant can be used for all kinds of pre-buried pipelines, through-wall steel bars, H-beams, pile caps and other waterproof.
●Various types of construction joints or structural cracks are leaked.
Water Swelling Polyurethane Sealant Safety&Storage
●Keep contents out of reach of children. In case of contact with eyes, please rinse eyes with plenty of water and seek medical advice as soon as possible
●9 months stored at dry below 25℃ unopened in original containers.
