ACA Applicators Technical Group 2020 Summary

The ACA Applicators Technical Group (ATG) was formed to represent the needs of specialist contractors in industries that serve the protection or restoration of corrosion affected structures throughout Australasia including New Zealand. These include companies and individuals in; concrete remediation and protection, applied concrete floor finishes, surface preparation and protective coating of steel and hazardous coating removal. The ATG, aligned with many other associations and technical groups, has been severely impacted by the restrictions imposed on our members with the cancellation of conferences, seminars and training courses. The ATG has proposed revised outcomes for 2020 and 2021 are as follows:

Copper Based Antifoulings on Aluminium Marine Vessels

Antifouling coatings for aluminium vessels have been a controversial subject for many years and for many years the use of organo-tin based coatings was seen as the most effective long term option. Organo-tin products are no longer an option and this has resulted in evaluation of alternatives. Traditionally the use of copper based products (Cuprous Oxide mostly) had been an effective option for steel hulls but were avoided for aluminium due to concerns with the interaction between the Cuprous Oxide and aluminium hull.

Preparation for Windtower Coating Using a Bristleblaster

The ACA hosted a presentation and product demonstration from Phil Chester, Managing Director of Montipower. In this webinar, Phil presents some case studies covering recent and ongoing projects where the Bristle Blaster is being used specifically for wind tower repairs. This presentation included a demonstration of the correct use of the tool and an explanation of the difference between the Bristle Blaster and an often confused tool in the market. Whilst Phil primarily discusses wind tower maintenance, the principle of preparation for coating a wind tower is virtually the same as any steel preparation when it comes to using the Bristle Blaster.

Managing Corrosion Using Integrity Operating Windows

Unexpected corrosion damage is just as likely to arise from defective process control & lack of recognition of potential damage mechanisms, as incorrect alloy selection.

Operating plant is subject to variability of service condition arising from changes in feedstock, temporary process upsets, shutdowns for inspection and restart all representing a significant challenge to reliable operation.  Corrosion damage mechanisms may proceed intermittently or steadily and time to failure may range from seconds to years and consist of initiation and propagation phases.
