Product Details
Summary
LD 332 is a kind of one-component polymer water plugging material formed by chemical reaction of isocyanate and water-soluble polyether.
Features
● With water as the crosslinking agent, the slurry will disperse, emulsify and foam itself upon contact with water to form an impermeable elastic gel like solid body, so as to achieve instant water stopping;
● One component grouting, low viscosity, good irrigability, large water multiple; At the same time, the viscosity and curing speed of the slurry can be adjusted according to the needs.
● The consolidated body formed after the reaction has good ductility, low temperature resistance, elasticity and impermeability. Permanently intact in water;
● The material expands and foams in contact with water, has the characteristics of secondary penetration, and has no pollution to water quality；
