SW-PU 500(PU V)


SW-PU500 is one liquid type soft foam urethane resin having strong hydrophilic type, Through injecting and putting leakage part of structure joint having vibration. It maintains high elasticity and blocks it from lnflow water with reaction to the water formation layer of open cell structure.

Owing to forming high-elasticity at the small amount of water and forming quick response partial gel at the large amount of water, it is the excellent product having no shrinking change.

  • Leakage part of structure having vibration.
  • Formation of waterproof curtain layer on the back of the structure

  • 10kg steel pail
  • 20kg steel pail
