  • mechanical edge preparation for paint application
  • decontamination of the substrate from dirt, oils and grease
  • decontamination of visually unidentifiable impurities
  • surface preparation according to ISO 8501-1 to purity grade Sa 2½
  • manual application of corrosion barrier POLYGLASS VE HA
  • carrying out the relevant quality tests according to the PKZ

CORROTECH ENGINEERING s.r.o. provides highly professional services in the field of surface preparation and application of special coating systems for the most demanding stress environments and various industrial equipment. POLYGLASS VE HA vinyl ester coating, designed for manual application and filled with special glass microflakes, is the ideal choice for corrosion protection of submersible pumps in chemical load operation, protecting the substrate of the steel structure against the effects of corrosion in the long term. The project was carried out in the workshop environment of our company in Most – Komořany and was subsequently shipped abroad.

CORROCOAT has been successfully fighting corrosion for more than 45 years. It uses innovative mechanical engineering combined with anti-corrosion technology to provide long-term protection for both new and damaged equipment. It uses special composite and structural coatings in conjunction with technical processes to individually address corrosion problems. With a focus on quality, refurbishment procedures are a proven, cost-effective weapon to win the battle against corrosion in the long term.
