Paint and coatings
Epoxy Paint and coatings
The applications making use of epoxy-enhanced coatings and paints benefit a wide range of sectors. The most common are construction (including flooring), shipbuilding, water and sewage treatment as well as home appliances. By bringing new performance characteristics to the material they coat or bond, epoxies improve efficiency and technical advantages superiority. Epoxy coatings include:
Primer tie coats
Heavy duty intermediates
Chemical-resistant tank linings
Heat-resistant coatings (up to 230ºC)
Industrial and everyday uses
Industrial applications are common in a number of sectors. Epoxies are used as protective and insulating coatings and primers to build ships and other vessels, aircrafts, spacecrafts and satellite systems. Due to their strength, they are used in the renewable energy sector to coat steel, wind turbine poles as well as to produce their blades, and protect the structures of hydroelectric power stations. Other relevant applications include pipes used for drinking water, waste, oil and gas.
In the construction sector, epoxies are used in structural parts, engineering adhesives and paints to enhance durability, strength and resiliency, guaranteeing longer lifespans and lowering the need for repainting and refurbishment. In applications such as flooring, they help maintain higher hygienic standards, as they allow the use of stronger cleaners. When used with materials such as marble, they also improve their aesthetic properties. Last, they are also used as fire protection on commercial and industrial installations.
Epoxies are widely applied as liquid pastes or mortars to coat the floors of shopping malls, hospitals, schools, prisons and industrial buildings.
In the food industry, epoxies can be found in cans and special packaging, where they are used as a lining to protect the contents from corrosion and the flavour of goods.
Finally, epoxies are used in household appliances as functional powder coatings, increasing resistance to chemicals, food acids, pollutants, sewage and water as well as protecting from corrosion, harsh conditions and wear and tear.
The most common products which are powder coated are refrigerators, washing machines, tumble dryers, etc. The coatings protect the appliances in any kind of situation, whether by supporting the metal casing to withstand mechanical abrasion, damage from bumps and other impacts or by protecting the machines from the chemicals used to clean them. Thanks to epoxies, appliances purchased today have an extended product service life and improved aesthetics, in comparison to a few years back.
The advantages of powder coatings made with epoxy resins are given by their enhanced performance properties compared to competing materials. The monomers, pigments and additives used in powder coatings are very tightly bonded together and provide a surface that is able to retain a like-new appearance for an extended period of time.
