Sydney -- Australian Urethane Systems recently supplied one of its potable water approved sealing solutions to seal a West Australian water treatment plant against various potential threats, including hydrogen sulphide.
The Polyeuro 1050H polyurethane coating was selected for this application due to its fast cure rate, toughness, resilience and elastomeric properties, Australian Urethanes said in a 29 May news release.. It was applied to an area of 6000m2 at the Alkimos water treatment plant.
The Alkimos water treatment plant serves the population growth of Perth's north west corridor, with a population expected to reach about 150 000 by 2030, the company said, adding that essential to growth and development in this region is wastewater and water infrastructure.
For application at the site, Polyeuro 1050H was used with a specific priming system to seal the porous concrete structure and enable a pinhole free coating.
Australian Urethanes said that once applied, the PU coating provided long term protection of the concrete structure against hydrogen sulphide damage, achieved an excellent bond to its substrate and provided a seamless coating to the roof and wall areas.
