A Breakthrough in Polyurea Technology


A Breakthrough in Polyurea Technology

Polyurea was developed as an insulator for the manufacturing industry. A fine example of such use is found in the automobile industry. With the invention of polyurea, car makers were able to reduce the size and weight of their vehicle’s engine by as much as 40 percent. This greatly increased gas mileage and efficiency.

Polyurea is also found in the pharmaceutical and cosmetic industry. Applications requiring a chemical resistance to solvents, UV radiation, biodegradation, and combustion have also found great demand in the polyurea market. With the invention of low viscosity polyurethane, which is an improved version of the typical polyurea, it has now become possible to combine these applications with high tensile strength and low elastic modulus.

Polyurea spray coatings are generally used for flat surfaces because they form very good mechanical and chemical barriers. It is important that you ensure that the surface preparation is effective and sufficient. Spray coatings generally do not adhere well to rough surfaces, so there may need to be some level of grinding before the application. The surface preparation must include an optimized emulsification and soaking of the ingredients. Prior to spraying, the surfacing material must be clean and dry.

Polyurea coatings are especially popular in the security sectors, particularly those that are exposed to harsh chemicals and conditions. Polyurea reduces the risk of surface damage due to impact, rust and corrosion and thus is used extensively in the military and security industries. However, the polyurea market is seeing a lot of competition and innovation from rivals keen to cash in on the polyurea success. Some polyurea products boast of instant impact resistance, while others offer greater durability.

There is also another type of polyurea that is in fact a derivative of the aliphatic polyurea family – the aliphatic polyaspartic. The aliphatic polyurea contains two hydroxyl groups rather than one as found in the polyurea family. Because of the hydroxyl group, the polyureaspartic can achieve a much higher degree of flexibility, which can reduce distortion, increase flexibility and cut down on surface wear and tear. However, the aliphatic polyurea tends to have a lower heat tolerance, and hence it is better suited for use where condensation accumulation is an issue or where you need an exceptionally fast cure rate.

Polyurea has been around for many years but recent developments have transformed it into a highly efficient and durable product. The polyureaspent manufacture process has made it possible to mass manufacture polyureas at low cost using standard equipment, reducing costs associated with scale and labor. Although polyureas has many advantages over other materials, its high cost relative to other polyurea alternatives makes it a less viable solution for manufacturers looking to cut manufacturing cost. However, new technological developments have brought about polyureasperthane, which is arguably superior to polyureas for many manufacturing applications.
