PJ Water Swelling Waterstop Glue Company

Product introduction: Water-swellable sealant is a single-component water-swellable, moisture-curing, elastic sealant independently developed by our company. It is based on polyurethane prepolymer and contains urethane paste with special grafting technology. After curing and forming, it has a dual sealing and water-stopping mechanism of volume expansion when exposed to water and elastic sealing and water-stopping. This product is mainly suitable for the waterproofing of construction joints (including post-casting tape), deformation joints and embedded components in industrial and civil construction underground projects, municipal tunnels, protection projects, mountain and underwater tunnels, underground railways, sewage treatment tanks and other projects, and Water leakage control in existing projects.
Product features:
Good water-stopping effect. It has the elastic water-stopping mechanism of rubber and the dual water-stopping mechanism of its own volume expansion seal when exposed to water. It has maximum resistance to water pressure. Strong durability and low quality change rate: The water-swellable sealant contains urethane linking chains with special grafting technology, which will not cause loss of expansion elements during long-term use. At a temperature of ℃, the theoretical life is years.
Convenient construction:
Single component, paste. A standard caulking glue construction gun or putty knife can be used for caulking construction. Good adhesion: it can be firmly bonded to concrete and other basic surfaces. The moisture content of the basic surface is required to be low, and it can be firmly bonded even if it is wet
Technology Environmental protection:
It has good chemical resistance: it can withstand chemical media such as hydrochloric acid, seawater, sodium carbonate, potassium hydroxide, etc. It can be directly used in drinking water projects. It is safe, non-toxic, and is an environmentally friendly product.
Good cost performance:
The performance is better than traditional construction joint waterproofing materials such as steel edge rubber waterstops or waterstop strips, and the price is moderate.
