It is resistant to the bacteriological conditions associated with sewage treatment and silt accumulations in water storage and is designed to meet many of the requirements of the water industry in water retaining structures, sewage treatment and sea defence works. The abrasion resistance of Nitoseal PU12 also makes it suitable for use in sealing movement joints in concrete sea walls subject to tidal scour.

  • Abrasion resistant.
  • Excellent adhesion under immersed conditions.
  • Resistant to aerobic and anaerobic bacteriological attack.
  • Separate component available for accelerating the initial cure.
