Fosroc Nitoseal PU12 | Biodegradation Resistant Sealant

Fosroc Nitoseal PU12

1986000
FOS8297

Fosroc Nitoseal PU12 is a two-part, elastomeric joint sealant based on polyurethane technology. It is supplied in packs containing base compound and curing agent in the correct proportions which, when mixed, cure to form a tough rubber-like material. Adhesion to most commonly used construction materials is excellent.

In special circumstances, such as sealing sea defence works in tidal areas, a special Nitoseal PU12 Accelerator component is available, to be added when mixing to enhance the initial cure rate, so that work can be completed between tides.

Description

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

Features & Benefits


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

Uses

  • Sludge digestion tanks
  • Filtration and aeration tanks
  • Culverts
  • Raw water reservoirs
  • Sea walls



Application Notes


  • The use of Fosroc Primer P7 is essential to ensure proper adhesion on porous surfaces
  • Allow the primer to dry. The sealant may be applied within the time period 30 minutes to 3 hours. That is after the primer solvent has evaporated but before the film has fully reacted. Any primed surfaces left longer than 3 hours must be re-primed before applying the sealant
  • Mix thoroughly using a slow speed drill (300 to 500 rpm) fitted with a Fosroc Sealant Mixing Paddle. Mix for 3 minutes then scrape down the sides and bottom of the tin using a spatula, mix for a further 2 minutes
  • Load the mixed Nitoseal PU12 into a Fosroc ‘G’ gun using a Follower Plate. Compact the Nitoseal PU12 into the primed joint. Tool off leaving a smooth finish
  • Can be finished by tooling-off smooth using a metal or wooden spatula. A minimum amount of detergent may be used to ease this operation. Remove all masking tapes immediately after tooling. Excessive tooling can cause surface drag, this should be avoided
  • Clean equipment immediately after use with Fosroc Equipment Cleaner
  • Coverage dependent on joint size. See product data sheet
