What is polyurea coating?

The polyurea coating adopts a one-time coating process, no matter how large the area is, there is no link seam, and it is also a dust-free material polyurea coating, which has the characteristics of strong adhesion, friction resistance, and strong hardness.

Feature
In the polyurethane system, in order to improve the reaction activity, a catalyst must be added. The catalyst catalyzes the reaction between the hydroxyl group and the isocyanate, and also catalyzes the reaction between the isocyanate and water, generating gas, resulting in a sharp decline in the performance of the material; the polyurea system is completely different, it uses Amine-terminated polyether and amine chain extender as active hydrogen components have extremely high reactivity with isocyanate components, and the reaction can be completed instantly at room temperature (even below 0°C) without any catalyst.
(1) The coating does not contain a catalyst, it cures quickly, and can be sprayed on any curved surface, inclined surface and vertical surface without sagging. The walking strength can be achieved within 5s of gel and 1min.
(2) Coatings are not sensitive to moisture and humidity, and are not affected by ambient temperature and humidity during construction.
(3) The coating has 100% solid content, does not contain any volatile organic compounds (VOC), and is environmentally friendly.
(4) It has excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, and corrosion resistance.
(5) It has good thermal stability, can be used for a long time at 120°C, and can withstand short-term heat action at 150°C.
