Rejuvinating tanks for Polyblend



ANALYSIS
  • Client: Polyblend
  • Location: Widnes
  • Work undertaken: Internal Lining & External Painting

Coating specialist Repair Protection and Maintenance (RPM) has lined and externally painted three stock tanks for Polyblend, one of the leading manufacturers and distributors of liquid polymers, polymer additives and resins.
The aim was to rejuvenate three aging tanks at Polyblend in Widnes, Cheshire, site that had been used to store stone placestercisers used in plastic moulding.
Using internal and external scaffolding, the three tanks were grit blasted on the inside to Swedish Standard SA2.5, with a minimum surface profile of 50 microns.

Once the dust had settled and been removed, two coats of Chemco RA 500M were applied to achieve a total nominal dft of 600 microns (500 microns minimum dft).
The lattice on the outside of the tanks was removed and the external surface was prepared to provide a suitable key, following which a coat of Chemco Rustfix was spot applied to achieve a nominal dft of 40 microns.
Once this was cured, a coat of Sigmacover 435 was also spot applied to achieve a nominal dft of 100 microns. Finally, a full top coat of Sigmafast HS Enamel was applied to achieve a nominal dft of 40 microns.

Says Polyblend’s safety/process engineer, Samuel Shomefun: “We used RPM because of its performance on other contracts it has carried out for us. It’s people have always done an excellent job for us, whatever they have tackled.”.
