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.

Contato com Produtos Químicos

Alguns produtos e insumos das unidades de processamento são corrosivos, e os equipamentos, tanques, tubulações e estruturas que permanecem em contato com estes agentes químicos e precisam de proteção diferenciada. A WEG também possui linhas de produtos especialmente desenvolvidas para suportar estas condições, que envolvem transporte e armazenamento de fertilizantes, insumos, ácidos e bases, equipamentos de mistura e de extração eletrolítica de minerais.

Regiões Portuárias, Marinhas e Industriais Agressivas

Regiões costeiras para embarque ou recebimento de material estão constantemente sujeitos a névoa salina e umidade, criando um dos piores ambientes corrosivos. Fábricas e unidades de processamento localizadas em regiões com alta concentração de poluentes também propiciam condições altamente agressivas.
