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

●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%.
●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.
●Safe and environmentally friendly:safe,non toxic,it 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.
●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.
●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.
Polyurethane Water-Swelling Sealant Safety&Storage
●Keep contents out of reach of children.
●12 months stored at dry below25°C unopened in original containers.
