Epoxy Primers Are Used for a Large Array of Industrial Purposes

If you ask an industrial professional about coatings or primers, he or she will normally be familiar with the term “epoxy”. Epoxy primers are often used because of their chemical resistance, strong bond, and durability. The coatings can also be applied in various ways including brushed on, trowelled on, or field applied. Coatings of this type are known for their heat resistance, unsurpassed adhesion, and mechanical properties.

In the industrial field, epoxy primers are often used for steel or concrete. The primers, as noted, adhere easily and therefore can be used to cover bare metal, fillers, other primers, or paints. Because of its non-porous finish, an epoxy primer is often advised as a base coat over steel. It can also be used on plastic, on fibreglass, or over a black iron phosphate coating.

How Epoxy Primers and Coatings Are Used

Besides structural steel and concrete, an industrial painter in Perth may also apply an epoxy primer on offshore platforms, in refineries, on barges, or as a coating on industrial equipment or the exteriors of railcars. Whilst epoxy serves well as a primer, it can be used as an intermediate coat or finishing coat as well.

Professionals in the coatings industry think of an epoxy as a must-have product. The coating can be applied underwater and is also suitable in applications where a high amount of heat is used. Typically, an underwater epoxy displays an excellent ability to adhere to most submerged surfaces.

However, if it is applied to a steel surface in salt water, difficulties sometimes arise. That is because surfaces of this type may be protected by a cathodic barrier. In other words, charges of electricity are used to prevent corrosion and these charges can disrupt the bonding process. Therefore, if an epoxy is used on steel in a marine setting, it is normally tested first.

Epoxy Advantages

Most epoxy primers, however, are well worth the investment as they offer a number of advantages to businesses. These advantages include the following:

  • Epoxies, as noted, bond well to concrete or metal, especially steel.
  • An epoxy coating provides a high chemical resistance and can withstand temperatures over 205 degrees Celsius.
  • A primer offers protection against abrasion.
  • When a primer or epoxy coating is used, if offers reinforced wear resistance and therefore lowers the risk of chipping or cracking.

Needless to say, when you work with a protective coatings company, it will feature epoxy primers on its list of coating services. You can also rely on the company to supply your coating needs with respect to zinc coating, polyurethanes, siloxane coatings, non-slip coatings, and high-temperature coating materials.

The sectors that are served in this respect include the mining industry, onshore and offshore drillers, and transportation companies. Coatings can also be used for protecting surfaces from graffiti or to line tanks.
