A protection coating that helps reduce waste

How using an anti-corrosion surface demonstrates commitment to the circular economy.

CuanTec, a chitosan biopolymer specialist plant in Scotland, recently invited a specialist to help provide anti-corrosion coating to the internal lining of three tanks being used to turn a shellfish byproduct into the biopolymer chitosan. Given the important role the tanks play in this transformation process, the company felt that safeguarding them against future damage was a business imperative.

COMMITMENT TO THE CIRCULAR ECONOMY

CuanTec is committed to a circular economic business model and the business has been designed to mitigate the carbon footprint caused by the unnecessary disposal of unused shell within the shellfish industry. Key to these efforts is careful maintenance of its business assets.

PRE-USED TANKS NEEDED ANTI CORROSION MEASURES

CuanTec chose to use three steel tanks to turn shellfish shell into high quality, traceable chitosan products, made to the exacting technical specifications of their customers. The tanks had already been in use elsewhere, but were otherwise in good condition. To ensure the tanks were capable of withstanding the harsh chemicals to which they would come into contact, the company decided to invest in some polymeric technology to protect them.

BELZONA RECOMMENDS HIGH PERFORMANCE COATING

Following an inspection from Clive Leadbitter, senior field sales engineer at a polymer technology specialist and authorised Belzona Distributorship, Belzona UK, the company selected the high-performance coating, Belzona 1391T. This system is capable of protecting assets against corrosion in extremely aggressive and acidic environments, making it the ideal solution for the steel substrate for this specific application.

In addition, Belzona 1391T can be applied in-situ without the need for hot work, and this meant that the application was carried out quickly, while minimising the health and safety risks that can arise when hot work is involved.

 

Commenting on the application procedure, Clive said: “Surface preparation was carried out by grit-blasting. Following this, two coats of Belzona 1391T were applied at a thickness of 450 m (17.72 mil) per coat using a stiff-bristled brush. Once the application had cured - around 24 hours - the application was complete.”
