Polyureas are made by passing fine sheets of resin through heat and pressure to create an ultra smooth surface. The term polyurea comes from the gaseous reaction between an isocyanic acid component and a synthetically manufactured resins polymerizer component during step growth polymerization. The isocyanic acid can be either aliphatic or aromatic in nature. It has been used for many years to create materials that have high wear resistance, abrasion resistance and natural lubricity.
Polyurea is commonly used in the printing industry as it has low viscosity which allows ink to pass with high printing speeds and excellent printer quality. It is also able to withstand high temperatures and is light weight so it can easily be applied to a wide variety of substrates. The polyurea market is made up of a number of different materials including polyurethane foam, polyurethane resins, polyurethane coatings, polyurethane fluid, polyurethane sheets, polyurethane foam boards and polyurethane powders. As with all products in the market polyurea has a wide range of applications. The material is also found in other industries like automotive fluid, cleaning fluids, cosmetics, pharmaceuticals, petrochemicals, water treatment, roofing materials and many more.
Polyurea is most commonly used as an industrial coating but there are many other potential uses including household application and even as a safety coating. The main reason polyurea has such an outstanding reputation for both its performance and its various other applications is because it is a one hundred percent safe commercial grade coating with no known contamination or toxicity hazard. Unlike oils, polyureas do not require any additives to increase their lengthening or heating ability. This means that polyurea does not interfere with the growth process of rubber or the natural lubrication process of most plastics. The flexibility of polyureas makes it ideal for use in many different industries.
Polyurea can be applied as either a protective coating or as a lubricant. In its anti-friction role, polyurea works well against friction between two moving surfaces and against the flow of water. Polyureas also work very well against oils and grease and also against hot surfaces. It will also prevent abrasion to a certain extend.
Polyurea is especially useful for high performance coatings where high moisture resistance is necessary. The moisture resistance ability of polyurea far exceeds that of any other material available on the market, which makes it highly suitable for many applications. It is also a very good moisture control solution as it contains no moisture resistant additives. Other important characteristics of polyurea are its thermo-physical properties (i.e. its thermal conductivity), mechanical properties (i.e. its compressive strength) and chemical properties (i.e.
