Water-swellable water-stop glue is a solvent-free, single-component elastic water-stop that swells with water. Sealant. It is a urethane paste based on polyurethane preform and containing special grafting technology. It has a dual sealing and water-stopping mechanism of elastic water-stopping of rubber and water-stopping by its own volume expansion when exposed to 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. After the surface has hardened (the water-stop glue has cured), the next concrete pour can be carried out.
Features of water-swelling water-stop glue:
Good water-stop effect: It has the elastic water-stop of rubber and the double-sealing water-stop mechanism of its own volume expansion after contact with water, which can resist the water pressure of. .
Strong durability: The mass change rate is low. The water-stop glue structure contains urethane connecting chains, which will not cause the loss of expansion elements during use. At normal temperature, the service life is more than 10 years.
. Convenient construction: single-component glue, standard caulking glue construction gun can be used.
Good adhesion: No matter whether the base surface is wet, smooth or rough, it can be firmly adhered to the concrete surface, and has strong adhesion to metal, rubber, wood, cement components, ceramics, glass, etc. Attachment.
, anti-sag, inlaid vertical seams and top seams will not flow.
. Environmental protection: 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. It is safe and non-toxic. It is an environmentally friendly product.
, Other properties: good wear resistance, good oil resistance, high mechanical strength.
Classification of water-swelling water-stop glue:
According to the water expansion rate, it can be: type and type.
