Description SKW-603/605 polyurethane plugging agent take foaming polyether, Toluene diisocyanate(TDI) or PAPI as main material,after chemical reaction,it generate high efficiency polymer waterproof plugging material.
Classified by different application and material feature:
1.SKW-603 water solubility polyurethane plugging agent.
2.SKW-608 water solubility polyurethane plugging agent(retardant).
3.SKW-605 oil soluble polyurethane plugging agent.

These proucts have proudced in our company for a long story, they have been used on shanghai subway,beijing subway,Xiaolangdi Water Control Project and others underground constructions.

Feature (1)Water solubility polyurethane plugging agent：One component, after 10-900 seconds chemical reaction with water,the spongy elastomer will be generated to stop water.Stop-water effect is good, construction is convenient, low toxicity, easy cleaning equipment.
(2) Water solubility polyurethane plugging agent(solvent-free )：One component,it is water solubility polyurethane plugging agent mixed with 30-40% anhydrous acetone.same effect as water solubility polyurethane.As it doesn't have slovents,uninflammable,it is convenient for transportation safety and preservation.
(3)Retardant water solubility polyurethane plugging agent：One component,no need slovents and additive during application,same effect as water solubility polyurethane.Construction is convenient,water-stop effectively, incombustible,it is convenient for transportation safety and preservation.
(4)Oil soluble polyurethane plugging agent：Two components.The rigid foam will be generated by chemical reaction which happened after the two components compounded in 10-630 seconds.Features: The rigid foam will not shrink, high intensity, quick foaming speed, obvious effective for water-stop.
