FIELD: production of bicomponent compounds having increased strength, sealing of membrane elements. SUBSTANCE: in polyurethane compound which comprises isocyanate component, hydroxyl-containing component and catalyst prepolymer on the base of 4,4,4′-diphenylmethanediisocyanate and mixture of polyoxypropylene glycols having molecular weight 200 and 2000 at ratio 61.5: 5.80:8.30-80.0:18.0:29.1 being used. Mixture of polyoxypropylene glycols having molecular weight 1000 and 2000 and nitrogen-containing polyester having molecular weight 200 at their ratio 0.01:0.01:1.40-73.60:75.00:31.00 is used as hydroxyl-containing component. Tin dibytulaurate is used as catalyst. Said sealing composition contains, mas. p.: hydroxyl-containing component, 1; isocyanate component, 0.80-1.22; catalyst, 0.013-0.016. EFFECT: increased strength of sealing composition.
