Case Study

Case Study – Effluent Scraper Steelwork


Engineering Industry, UK.

Application date

October 2020.

Scope of work

External corrosion protection subject to sludge effluent at ambient temperature.


Polyglass VEF.

Corrocoat Armagel.

Coating system

  • Abrasive blasted externals to ISO 8501-1 to Sa2 1/2 with a minimum surface area of 50 microns.
  • Completed final blow down, sweep and vacuum clean to remove dust.
  • Applied Polyglass VEF to achieve DFT of 500 microns.
  • Applied  Corrocoat Armagel internally to achieve minimum DFT of 1000 microns.
  • Thickness checked and spark tested.
  • Packed and prepared for dispatch.

Coating credentials

Polyglass VEF: A glass flake vinyl ester acrylic co-polymer. Excellent in immersed environments. Excellent flexibility, undercutting resistance and sliding abrasion resistance.
