Description

MAXLINE 100 - Potable Water Coating

MAXLINE 100 – Potable Water Coating is a WRAS approved solvent-free polyurethane coating system. Specifically designed for relining potable and drinking water tanks and provides excellent protection against erosion and corrosion.

Once cured the product is extremely flexible and will breathe with the tank as it cycles from full to empty without any risk of cracking.  

Maxline 100 will have a design life in excess of 10 years. We offer a full application service through our network of approved 3rd party contractors, please do not hesitate to contact us for further details.

Application Guide

  • All oil and grease must be removed from the surface using an appropriate cleaner such MEK or similar type solvent.
  • All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
  • Once blast cleaned, the surface must be degreased and cleaned using MEK or similar type solvent.
  • All surfaces must be coated before gingering or oxidation.
  • All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
  • All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
  • Once abraded, the surface must be degreased and cleaned using MEK or similar type material.
  • All surfaces must be repaired before gingering or oxidation occurs.

Prior to mixing please ensure the following:

  • The base component is at a temperature between 15-25°C.
  • Do not apply the material when the ambient or substrate temperature is below 10°C or less than 3°C above dew point.
  • Transfer the contents of the Activator unit into the Base container.
  • Using a slow speed electric paddle mixer, mix the 2 components together until the material is streak free.
  • Once mixing is complete, use the mixed coating as soon possible after mixing.

Use all mixed material within 15 minutes at 20°C.

  • Pour the mixed material into a paint kettle or paint tray (this will maximise the usable life)
  • Using a 50mm synthetic brush, stripe coat all edges, joints & corners.
  • Once the stripe coat has cured sufficiently and is capable of being overcoated, apply the basecoat to all surfaces at minimum 500 microns.
  • Once the basecoat of material has cured sufficiently, approximately 6-8 hours at 20°C, apply the topcoat to all surfaces at a minimum 400 microns.

Minimum finished coating thickness needs to be in excess of 800 microns.
