POLYUREA MANUFACTURER

Polyurethane and polyurea have similar names that reflect their closely related chemical structures, which results in both materials also exhibiting similar physical properties. Both materials are elastomers used for protective coatings, but polyurea cures faster, offers better moisture resistance, and displays superior durability compared to polyurethane for most applications. 

Crazing refers to the formation of small cracks in the surface of the coating due to shrinkage after application. Micro-fracturing involves deeper cracks caused by increased coating stress due to the expansion or contraction of substrate materials beneath it.

The best way to prevent polyurea coatings from cracking is to prepare them carefully before application and properly cure afterward. For example, make sure that all surfaces are clear from dirt, dust, grease, oil stains, etc., before applying the coating, as these can cause adhesion failure, which could lead to cracking down the line. Also, be aware that some substrates are prone to absorption when wetted: if dampness has occurred from snow melt or rainfall, for example, then additional time should be taken for adequate drying before application so as not to risk shrinkage during cure time later on, which could again result in craze cracking over time. Finally, ensure that you follow your manufacturer’s instructions and adhere strictly to their recommended drying times for optimal performance; any deviations here will also strain your polyurea.

When applied correctly and properly cared for, polyurea & polyurethane coatings can last more than 25 years. The same exceptional weathering and abrasion resistance that affords their widespread use is also responsible for their long lifetime, protecting surfaces for decades after application.

Polyurea coatings can be applied to almost any surface, including metal, concrete, and fiberglass, perfect for coating a wide range of different structures and equipment. This versatility has seen polyurea applied across countless industries, from automotive and agricultural to construction and even military.
