Polyurea – A Popular Conventional Coatings
Polyurea, also known as resin polyurea, is a kind of synthetic elastomer which is derived through step-growth polymerisation from an organic polymer component and an artificial resin ingredient. This polyurea is usually, but not always, colorless or translucent. It is usually mixed with other materials at a formulation. There are various grades of polyurea resin and each has its own properties.
Polyureas are elastic and can be shaped like a brush. They have a wide range of uses in many industries such as agriculture, construction, marine, automotive, pharmaceutical, cosmetic, petrochemical, aerospace and the like. The main reason behind their wide-ranging uses is their unique physical and chemical properties. Polyureas have an extended molecular structure which enables them to exhibit a wide range of mechanical properties such as tensile strength, compressive strength, electrical and thermal conductivity, lubricity, friction and adhesion. These unique physical and chemical properties make polyureas suitable for a large number of applications. Moreover, they also provide a large number of opportunities for researchers to explore the fundamental chemistry and technology of polyureas.
Polyurea is used as a barrier to prevent the penetration of moisture into a working surface or container. As the result, there is a reduction in the temperature of the surrounding area. Polyurea, through its moisture barrier, can also prevent the growth of bacteria and fungi. Additionally, polyureas can increase the structural integrity of a structure due to its thermal resistance. As a result, polyureas has great potential as a protective coating for any part of a structure from metal to non-metal surfaces. It has also been found to be useful as an antimicrobial, as it contains alcohols which destroy microorganisms present in surfaces and containers.
Polyurea can be applied as spray coatings on a variety of substrates including metals, non-metals and ceramics. However, polyureas have specific spray coatings applications which are more suited for applications and coatings which require smooth surfaces. In addition, polyurea usually includes an amine formulation for resistance to oxidation. When using polyurea as a coating, the amine coating is usually combined with an xylan-dipropionyl formula for the development of rigid polymer coatings.
Polyureas are flexible and cost effective. They have a wide range of applications and are suitable for a wide range of industries. For example, polyureas have great potential as heat shields for heat treatment applications. Polyureas are also widely used in the automotive, aerospace and marine industries for protection of brakes and other components. In the automotive industry, polyureas has emerged as a popular replacement for conventional oils, transmission fluid and coolant. Polyureas also serves as a lubricant between engine parts and the wheels, and has excellent thermal characteristics.
Polyurea‘s wide range of industrial uses makes it a superior coating choice than many different formulations available. In fact, polyureas have the ability to be formulated in several ways so that the user can achieve the desired effect. There are many different formulations of polyureas available for coating different components, such as stainless steel, aluminum, polycarbonate and glass. Each of these formulations has its own advantages and downfalls and polyurea offers the versatility and benefits of many different formulations in one convenient coating solution.
