Special price Jiangsu Shangrao single-component polyurethane water-swellable water-stop glue high modulus black national standard type
Minimum order quantity
Water-swellable water-stop glue is divided into types according to the water expansion rate Water glue and waterproof glue. Among them, the tensile strength of the water-stop glue reaches above 1.0, and the water pressure resistance is . The tensile strength of the water-stop glue is above . and the water pressure resistance is above .
Water-swellable waterproof glue is a water-swellable, single-liquid, elastic sealant. It is based on a polyurethane precursor and contains specially grafted urethane. It has a dual sealing and water-stopping mechanism of rubber's elastic water-stopping and its own volume expansion water-stopping after contact with water. It is suitable for waterproofing concrete construction joints and preventing leakage of various types of embedded components. Water-swellable water-stop glue can cure in humid environments. Curing time depends on ambient temperature and humidity. The higher the temperature or the greater the humidity, the shorter the curing time. Once the surface has hardened (dry to the touch) it is ready for the next concrete pour.
Essential Features: Good water-stopping effect. It has a double-sealing water-stopping mechanism of rubber's elastic water-stopping and its own volume expansion when exposed to water. It has strong durability and low mass change rate. The water-stopping glue structure contains urethane connections. The chain will not cause the loss of expansion elements in the long term. At normal temperature, the service life is more than 10 years. It has good slow expansion and is very suitable for humid and watery construction environments. Convenient construction. Single component, gel material, standard caulking can be used. The adhesive construction gun can stick firmly to the concrete surface regardless of whether the base surface is wet, smooth or rough. Environmentally friendly, it has good chemical resistance and can withstand hydrochloric acid, salt water, sodium carbonate, potassium hydroxide and other chemicals. It can come into contact with drinking water, is safe and non-toxic, and is an environmentally friendly product.
