Coatings
WEG’s Coating Business Division has been providing industrial and anti-corrosive coatings for over thirty years to manufacturers of machines, equipment and metal structures with experience in the mining sector. Designed to meet the different requirements of ore extraction, processing and transportation, WEG’s specialist durable coatings aim to reduce corrosion and fatigue and cut down on maintenance ensuring higher productivity over time through fewer shutdowns.
Exposure to chemical and corrosive materials, high humidity and abrasive materials in production, processing and handling during ore extraction generate a demand for high-performance coatings.
Excess of dust and humidity
Excess dust in the extraction, crushing, sieving, grinding and handling of ore and cement is inherent, in many situations the extraction occurs in humid environments. This means that the coatings on the machines, equipment, conveyor belts and metal structures must be highly resistant, easy to apply and cost effective.
WEG double-function epoxy line, together with the polyurethane topcoat meet the requirements for these processes and are recommended for construction through to maintenance.
Immersion and direct contact with liquids
During production, the use of separation techniques based on gravity, flotation or leaching exposes equipment to continuous contact with liquids, often in extremely aggressive environments. Pipes and metal frames that are buried or submerged in fresh or salty water also require protective coatings.
WEG’s technologically advanced resins ensure excellent performance as indoor or outdoor coatings for pipes, storage and mixing tanks, flotation columns and cells, decanters, dewatering systems, thickeners, clarifiers and filters.

Contact avec les produits chimiques
Certains produits et additifs utilisés par les unités de traitement sont corrosifs et l'équipement, les réservoirs, les tuyaux et les structures en contact avec de tels produits chimiques doivent être particulièrement protégés. WEG développe également une gamme de produits conçus pour répondre précisément à de telles conditions, qui font référence au transport et au stockage des fertilisants, des additifs, des acides et des bases pour l'équipement de mélange et celui dédié à l'extraction électrolytique du minerai.
Domaines industriels agressifs du secteur portuaire et maritime.
Les zones côtières dédiées au chargement et à la réception de matériel sont continuellement sujettes aux projections d'eau salée et à l'humidité, ce qui en fait l'un des environnements les plus corrosifs. Les usines et les unités de traitement, où la concentration en polluants est élevée, sont également soumises à des conditions agressives.
