Polyurea Coating and Different Applications

Polyurea spray coating is one of the most advanced polyurea products on the market today. Durability. Polyurea is an extremely durable material with an extremely high level of thermal flexibility, making it perfect for demanding working conditions such as truck bed linings. It’s also chemically and water resistant. Temperature tolerance. Polyurea coatings can be safely used above a wide temperature range, with no loss of chemical or physical protection.

Polyurea coatings are much more flexible than standard waterproofing materials such as vinyl and rubber. This means that polyurea protective coatings offer many advantages over other forms of waterproofing including conventional foam-based waterproofing. The polyurea coating can also perform much better than other forms of waterproofing, providing superior protection against moisture and water.

There are many benefits to polyurea waterproofing. However, it’s important to understand that polyurea coating is not a magic solution that will make your project leak proof. There are several key components to effective waterproofing including proper surface preparation, proper sealing, and the proper application. Once you’ve performed all three of these steps and your project is complete, there will be some measure of residual barrier above the polyurea coating, but this will be invisible to the naked eye.

Polyurea spray coatings can be applied over any surface including metal and wood. If corrosion is a concern, polyurea coating will reduce the overall corrosion resistance of the surface by forming a more rigid coating that cannot readily break down. This can reduce the structural integrity of the structure by increasing the likelihood of premature failure. The coating will not prevent rot or weathering, however. It’s important to consult with an engineer if you have concerns about how your coating might affect your structural integrity.

Polyurea coatings can also be applied with an abrasive, which will reduce the thickness of the coating and can increase its effectiveness. However, the primary use of polyurea coating is in high pressure hot spray applications. In such applications, the high pressure hot spray will create stresses within the material causing it to crack, flake and bubble, sometimes resulting in release of polyurea into the air.

Most polyurea coatings contain calcium thioglycolate (CTA), which is commonly referred to as humic acid. Humic acid is commonly used as an abrasive in abrasive coatings such as concrete and tile because it helps to increase the amount of friction that exists between particles of material that don’t currently have contact. Because CTA is insoluble in water, it must be derived from a chemical that can penetrate the skin. Polyurethane is generally derived from petroleum or animal fat; the other two substances most often used are mineral oil and alkyl or lignin alcohols.
