Many times, coated objects are too big to cure in practical circumstances. In this case coated objects will cure once the object has been put into service. When in service, usually temperatures of 150 °C and higher are obtained. After being exposed at temperatures of 150 °C for 8 hours the paint film will be fully cured. The time between coating application and heating up may take several months. In the meantime, the paint film protects against water and light influence.
