Corroless ACO Mastic Rapid Grade is a solvent free, fast curing, two pack polyurethane repair mastic for pipe coatings.

Features

  • Use for the coating of field joints, repair of damaged coatings, filling of holes and cracks, on steel pipelines and other steel structures
  • This Rapid grade is specifically developed for use at lower ambient temperatures. For temperatures above 25oC the Mastic Standard Grade should be used, as this Rapid grade will be too fast curing

Surface Preparation

  • All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams
  • Steel: blast clean to minimum Sa2½ (ISO 8501-1:2007), surface profile depth 75-100µm. Mechanical tools may also be used providing a profile of minimum 75µm. Do not polish the steel surface
  • Overlap onto existing pipeline coating: remove any loose material to establish a firm edge. Feather sound coating and abrade surface to provide a key. Thoroughly abrade to remove gloss, surface contaminants etc. by suitable method (sweep blasting, abrasive disking etc.)
  • Concrete: remove all laitance and other contaminants by most appropriate methods. Ensure the concrete is dry to a reading of <16% on the Wood Moisture Equivalent (WME) scale. Prime with Corroless ACO LV Sealer

Mixing

Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator. Activator must be added to base and thoroughly mixed to ensure an even mix throughout the container – at least 2 minutes mixing time is recommended.

Care must be taken to avoid unmixed material being left on sides and bottom of can. Decanting mixed material into a plastic container and further mixing is recommended. Plastic container may be recovered for further use when coating has cured.

Thinner

Do not thin

Cleaner

Axalta Thinner Fast Industrial TH120 (formerly called No.4 Thinner)

Application Conditions

Do not apply when rain, mist, sleet or snow are imminent. Normal application requires relative humidity below 80%. To avoid risk of condensation, application should be performed only when the steel surface temperature is at least 3°C (5°F) above the dew point. Application at temperatures below 1°C (33°F) must be carefully monitored, since the possible presence of ice on the surface (or in pores, in the case of concrete) will result in poor performance.

Product Notes

  • Activator contains isocyanates – refer to Safety Data Sheet
  • Overcoating - abrading will be required if overcoating after 24 hours
  • In-service temperature limits: Wet – 0oC to 70oC depending on solution; Dry – minus 20oC to + 120oC continuous
  • In order to comply with WRAS certification, a minimum cure time of 14 days at 7oC is required before contact with drinking water
  • Corroless ACO Mastic Rapid has excellent adhesion to abraded Fusion Bonded Epoxy(FBE), and suitably prepared 3LPE and 3LPP.
  • Can be used in operations requiring fast cure, e.g. lay barge, weld coating and encapsulation of anode connectors, coating repair prior to trenching/backfilling. Corroless ACO Standard Mastic should be used for less speed-critical coating operations and at temperatures above 25oC
