Anti-corrosion coatings-a 'dark horse' in the coating industry

Anti-corrosion coatings-a 'dark horse' in the coating industry2019.11.28

Anti-corrosion coatings are widely used in modern industry, transportation, energy and marine engineering. They can be divided into conventional and heavy type anti-corrosion coatings according to the corrosion resistance and use requirements.


Conventional anti-corrosive coatings can be used in the general conditions to protect the metal from corrosion and help extend the service life of non-ferrous metals; heavy anti-corrosion coating is a kind of anti-corrosive coating that can be applied in a relatively harsh environment and it usually has a longer protection period than conventional anti-corrosive coatings.


anti-corrosion coatings applications


Anti-Corrosion Coatings Developing with Multi-Functions and Multi-Directions


There are more than 1000 varieties of anti-corrosion coatings in China, the traditional classification by resin are epoxy, epoxy asphalt, asphalt, chlorinated rubber, chlorosulfonated polyethylene, polyvinyl chloride, perchloroethylene, urushiol resin, ethyl silicate, high chlorinated polyethylene, polyurethane, polyurethane asphalt, phenolic aldehyde, and alkyd paint, etc.


In recent years, many modified resin anti-corrosion coatings with excellent properties have mushroomed on the market, such as alkyd resin modified polysulfide rubber modified epoxy anti-corrosion coatings and acrylic modified alkyd enamel used for railway passenger cars, and other anti-corrosive coatings like epoxy urushiol, urushiol silicon heavy anti-corrosion coating, etc.


At present, the new generation of anti-corrosive coating system has gradually occupied the mainstream of market. Environmental anti-corrosive coating, such as water-based epoxy and water-based acrylic coatings, have come out one after another, and enriched the varieties of anti-corrosive coatings.

Increasing Market Demand and Wide Applications


There are about one hundred manufacturers in China producing anti-corrosion coatings which can be used in various purposes.


At present, China's anti-corrosion coatings are mainly used in chemical and petroleum industries, railways, roads and bridges, metallurgy industries, power and energy industries, machinery and textile industries, automobile, ship and container industries.


Chemical and petroleum industries has the largest demand in anti-corrosion coatings, including oil field facilities, oil pipelines, offshore platforms, steel structures of petrochemical plants, etc. At the same time, construction and maintenance of railway and bridges are also the key field of anti-corrosion coating application, in addition, industrial products, automotive, marine industry are also the most potential markets for anti-corrosive coatings.

Environmental Friendly Anti-Corrosion Coatings Are Becoming Popular


Anti-corrosive coatings in China are developing towards high performance, high efficiency, low energy consumption and low pollution. Some waterborne anti-corrosion coating production enterprises have adopted the raw materials with low pollution for production. Producers have eliminated the use of banned coating materials, and use the more environmentally friendly materials in order to reduce emissions.
