It is one-component,polyurethane,water swelling sealant.
●Excellent adhesive to different surface
●Good expiation rate to protect fresh concrete during solidifying
●Durable water sealing
●Various products for different task
Surface dry time，h≤
Bonding strength to concrete土，MPa≥
Water expansion (room Temperature, distilled water)，﹪≥
Applied in waterproof structure,cross section of fix water stop or preventive injection hose.
●Pipeline and concrete iron in wall or cement board
●Surrounding the concrete iron or joint
●Inner joint of cable
●Preventive injection hose: type LWRI,I and II
●Cross section of water stop
Base surface must be sound,clean,dry,no oil or dust,etc.
Clean all practical,demolding agent,bleeding cement,old coating film and other loose animals.
Base surface temperature. Min+5℃ Max.+35℃
Environment temperature. Min+5℃ Max.+35℃
Base surface humidity Dry and no visible water
■Applied for fixing water stop or placing injection hose.
Apply the sealant on base surface,if base surface is not flat,nozzle size need to be changed.
Fix water stop and injection hose to the sealant. Concreting 2 hours after sealant solidify .
■Applied for sealing of the construction joint
If the triangle nozzle is used, refer to the following instruction:
Size of the triangular section
Length of the extrusion 600 ml/bar (theory data)
Length of the extrusion 320ml/bar (theory data)
Actual length of extruded sealant may be shorter because of condition difference.
■ Apply the sealant flat in the middle of concrete section.
Concrete edge: 10cm (reinforced concrete ) or 15cm (non reinforced concrete)
Concrete height: ＜50cm------- solidifying time:2-3 hours
Concrete height: >50cm-------- solidifying time:2 days
Press the sealant tightly during concreting to avoid cellular holes.
clean all the tools and equipment when process finished
Swell sealant will expand some hours after water contact. It is not allowed to stay a long time in water (water draining complete in 24 hours) before concreting.
Placing the sealant in movable crack is not allowed.
When water level rise,the sealant expand and sealed the crack.
In drying condition,the sealant shrinks to original size,but will re-expand when touching water.
Suggest to apply the sealant under less than 2 bar pressure(test pressure is 5 bar) because of sealing width limit.
If the pressure is high than 2 bar,the sealant can be used to fix the injection hose.
12 months(sealed packing,Temperature.+5℃---+25℃,drying condition)
