Abrasion Resistant Epoxy Coatings  

Epoxies are a type of chemically crosslinked or thermoset polymer structure that are commonly used as coatings due to their excellent adhesion, chemical resistance, and mechanical properties. Epoxies can be formulated to provide excellent abrasion resistance, making them ideal for applications where heavy wear and tear are expected. 

Abrasion resistant epoxies typically contain inorganic fillers which provide additional hardness and wear resistance. These coatings can be applied in a single layer or multiple layers to achieve the desired level of protection. 

One of the main advantages of using abrasion resistant epoxies is their ability to provide strong bonds to a variety of substrates, including concrete, steel, and other metals. This makes them a popular choice for use in industrial settings such as factories, warehouses, and processing plants where corrosion on tanks, structures, pipelines and environments with high slurries are found. 

Abrasion Resistant Polyurethane Coatings  

A polyurethane coating is generally more flexible and pliable than an epoxy. They can be formulated to provide a wide range of properties, including high abrasion resistance. Polyurethane coatings are commonly used in applications where there is a high degree of abrasion or wear or even impact, such as in marine environments or in heavy machinery. Erosion and corrosion resistance are crucial in these areas. 

An abrasion resistant polyurethane coating typically contains a high concentration of flexible backbones, which provide excellent toughness and resistance to wear. These coatings can also be formulated to provide other desirable properties, such as chemical resistance or UV stability. and they come in various colors to adapt to a number of applications, though a black coating is most common. 

Polyurethanes coatings are not only directly used on infrastructures, bulk storage tanks and processing equipment, but are also often used as topcoats over other coatings, such as epoxies or primers, to provide additional abrasion resistance and protection. They can also be used as standalone coatings in applications where the primary concern is abrasion resistance. 

Conclusion 

Abrasion resistant epoxy polymer and polyurethanes coatings are both excellent options for protecting various surfaces and processing equipment from wear and tear. The choice of which coating to use will depend on the specific application and the desired properties, such as particle size, concentration, flow rates, chemical resistance or UV stability. By selecting the appropriate abrasion resistant coating, you can extend the service life of your equipment and structures thereby lowering maintenance cost and reducing equipment downtime.
