While polyurethane technology ‘s been around for quite a while, the ability to harness it to create today’s incredible polyurea coatings is a relatively new development. As a result, some people have no idea of the benefits of this groundbreaking coating technology, or may be surprised when they hear what a simple coating is capable of.

Here’s a breakdown of what polyurea coatings are, what they’re used for, and what they can do:

What are the most common uses for polyurea coatings?

Polyurea are most commonly used as protective coverings over steel or concrete substrates, due to the robust protection they offer against rust and their high abrasion resistance. Other uses for polyurea include caulking and joint filling, this can fast set nature, incredible durability, and exceptional elongation characteristics. Polyurea mixtures can also be molded by spraying it into quick release molds as well as being applied as coatings polyurethane.

What does polyurea mean?

Because the term “polyurea coatings” is being used so frequently in the industry right now, many people have the misconception that it refers to one specific type of coating or a system of coating. That’s not the case. Instead, “polyurea” describes the unique technology used to create the special polymers that give polyurea coatings their incredible range of characteristics.

How should polyurea be employed?

Polyurea can be created to have many different characteristics and to fulfil many different needs. In part because of these differing formulae and in part because application methods will change depending on the requirements of the consumer, there are several strategies for applying polyurea coatings. Ideally, polyurea coatings should be applied by a professional who understands the unique needs and requirements the client has for the coating in question. This professional can then make the correct mix, obtain the specific product equipment required for the type of application planned, and prepare the surface to which the coating will be applied in line with the client’s asks for. They’ll then determine whether a primer is critical, and if so which primer should be used, and apply the coating to meet the client’s needs.

Benefits

Polyurea have very little aroma in fact, some products are completely odourless. They’re also VOC-free. polyurea coatings can be created to meet USDA approval and can be used on potable water systems. Polyurea are extremely resistant to thermal shock after curing, but they’re also surprisingly tolerant of varying temperatures during application they will cure completely at temperatures only -25 degrees Fahrenheit and of up to 300 degrees Fahrenheit. They’ll even cure under high-humidity conditions. These coatings are exceptionally flexible and can even bridge spaces in the substrate, something few other coatings are capable of. They’re also waterproof, and can be employed in almost any requested thickness in one pass.

Polyurea coatings are also very durable, and have superior bond strength when the chosen substrate has been properly prepared. They have a low permeability and are highly resistant to many damaging substances, including caustics, acids, and solvents.
