Single component polyurethane water-swelling sealant is a kind of polyurethane type amorphous paste with one-component, solvent-free, water swelling. The amorphous paste ensure that it can be used to prevent infiltration in irregular base. It has double sealed water stop function. Single component polyurethane water-swelling sealant not only has elasticity water stop of rubber but also has volume expansion stop water after soaking. And it can be cured in humid environments. Curing time depends on the temperature and humidity of environments. Compared with waterstop, it can be used in various irregular seams, especially between different materials, wet, pile head and other parts. And it also can be used in vertical surface without sag. Water-swelling sealant can be divided into two kinds according to the swelling ratio: PJ220 and PJ400. It is the economic choice for customers.
