A polyurea coating is a type of epoxy that protects almost anything from aging assets to emergency response vehicles. This type of protective coating is highly effective in reducing repair costs and extending the service life of critical equipment. It is ideal for a number of applications, from infrastructure to custom sculptures, and is available in a wide range of colors and formulations. Whether your vehicle is in an industrial setting or at home, a polyurea coating can make a significant difference.
The main component of a polyurea spray coating is an amine-terminated propylene oxide or ethylene oxide polyether. This coating contains a blend of chain extenders and polyetheramines. This material contains an average molecular weight of 200 to 5000 g/mol, and can be cured in as little as four hours. The various types of amines used in polyurea are listed in Table 3. The primary amide group in polyurea provides rapid reaction with the NCO group in the isocyanate component.
Other applications for polyurea coating include roof top coatings, car parking lot coatings, containment liners, and bridges. These products are versatile and have a long shelf life, but the drawbacks include tedious application processes, poor adhesion, and UV stability. Listed below are a few of the more common types and their benefits. You can read more about them below. Soil preparation and cleaning are two of the most important factors in ensuring a strong adhesion of a polyurea coat.
A polyurea coating must be properly applied to achieve the desired results. In order for it to be effective, it must be completely wet out before it sets. Otherwise, the coating may not adhere to the substrate and may change color. If you’re unsure about the right application method, ask a polyurea spraying specialist for a consultation. The initial investment in equipment is considerable, but will pay off in the long run.
Traditional polyurea was limited to pipe coatings and sewer linings, where it cured quickly and was used as a sealant for aging cars. Its high abrasion resistance and ability to resist rust and corrosion make it an excellent choice for construction and maintenance applications. Its versatility also makes it an excellent choice for car park decks and other outdoor surfaces. There are many other uses for a polyurea coating, but these are the most common.
Polyurea has numerous uses. It can protect aluminum and steel. It can also line water and sewer pipes and can be applied to hulls, bilge liners, fish hold liners, and fiberglass. Its elongation rate is higher than that of epoxy, so polyurea is ideal for a variety of applications. Its high resistance makes it a desirable choice for a number of industries. It is easy to apply and has an excellent elongation rate.
