While polyurethane technology has been doing for a time, the ability to harness it to create today’s incredible polyurea coatings is a relatively new development. As a result, some people have never witnessed 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 corrosion and their high damaging the teeth resistance. Other uses for polyurea include caulking and joint filling, because of the fast set nature, incredible durability, and exceptional elongation characteristics. Polyurea mixes can also be designed by spraying it into quick release molds as well as being applied as coatings. polyurea
What does polyurea mean?
Because the term “polyurea coatings” is being used so frequently in the industry right now, many people have the false impression that it refers to one specific type of coating or a system of coating. That’s incorrect. Instead, “polyurea” describes the precise technology used to create the special polymers that provide polyurea coatings their incredible array of characteristics.
How should polyurea be applied?
Polyurea can be designed to have many different characteristics and to fulfil many different needs. Partly because of these different formulae and partly because application methods will vary 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 precise needs and requirements the client has for the coating in question. This professional can then formulate the correct mix, obtain the specific aerosol equipment necessary for the type of application planned, and prepare the surface to that your coating will be applied in line with the patient’s desires. They’ll then determine whether a primer is important, and if so which primer should be used, and apply the coating to meet the patient’s needs.
Polyurea have very little odour in fact, some formulations are completely odourless. They’re also VOC-free. polyurea coatings can be designed to meet USDA approval and can be used on potable water systems. Polyurea are extremely resistant to winter shock after curing, but they’re also surprisingly tolerant of varying temperatures during application they will cure completely at temperatures as far as -25 degrees Fahrenheit and – 300 degrees Fahrenheit. They’ll even cure under high-humidity conditions. These coatings are exceptionally flexible and can even bridge fractures in the substrate, something few other coatings are capable of. They’re also waterproof, and can be applied 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.
