Polyurea is polyurea‘s most common structural polyurea derivative. It is also known as ‘waffle board’. Polyurea was first developed by J.M. Douglas and C.G. Gill who were working for the Douglas Aircraft Company in Cleveland, OH. They are credited for developing the polyurea float commonly used today.
Polyurea is primarily used as a structural lubricant and moisture barrier in high-performance products such as airplane controls, air bags and shock absorbing materials for industrial and manufacturing applications. Polyurea is also commonly utilized in dry cleaning, aerospace and automotive fluids, coatings, oils, lubricants, seals and other sealants for a variety of fluids. Polyurea can withstand extreme temperatures and stresses, is non-toxic, and extremely elastic under various operating conditions. Polyurea has multiple applications and can be formulated to meet diverse customer requirements. Polyureas can resist hydrostatic pressure, tensile strength, and any combination of cold closing and opening pressures as well as creep and deformation.
Polyurea has excellent chemical resistance properties which make it ideal for high-tempered components, especially aerospace metals and alloys. Polyureas provide low density, high stiffness index, and good thermal conductivity.

Polyurea coating thicknesses can be customized to meet specific coating needs and requirements. The material can be formulated to provide a low density, high tensile strength, or a high thermal conductivity finish. In addition polyurea is also used to protect steel shaft seals, polymer tubes, and aluminum components.
The coatings do not need additional treatments such as buffing and sealing. Polyurea coatings are resistant to abrasion, crushing, scratching, erosion, and chemical precipitation. Also the polyurea coating system requires no physical contact between the coating and the base material which eliminates an extensive amount of clean up. Coatings do not contain elastomers and silicone and therefore provide protection against UV, airborne, and physical impurities. Also the coating system does not affect the mechanical properties of the product, leaving it unaffected during processing or shipping.
Polyureas are available in various coating thicknesses to meet the application’s needs. Coatings generally include a lubricating, protection, and cushioning layer. Other optional features include wear resistance, heat conducting properties, chemical resistance, abrasion resistance, and thermo-stability. Abrasion, crushing, and environmental exposure are the main causes for premature coating removal.
Polyureas are used for many applications such as automotive bumpers, floor mats, tool coverings, shock-absorbers, seals, lubricants, sealants, and springs. Polyureas have excellent thermal qualities and extreme wear resistance even at elevated temperatures. They are resistant to abrasion, crushing, and scratching. Their chemical resistance allows them to be applied on the outside of most liquids and can stand up against high temperatures ranging from 100 degrees C to 500 degrees C. Polyureas have excellent hot tire repair and performance characteristics when treated with a high performance water/fat dry lubricant.
The material is flexible and durable enough to meet the challenge of any given project and perform flawlessly. The polyurethane coating can withstand heavy loads and high temperatures as well as resist abrasion, crushing, and moisture resistance. Due to its unmatched performance characteristics, polyurethane is highly demanded by the automobile industry, not just as a lubricant, but also as an environmentally friendly lubricant, flame retardant, shock absorbent, and anti-corrosive agent. With polyurethane coatings and other polyurethane products that meet your specifications, you can expect your products to perform longer than your competitors.
