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.
