Humidity and heat resistance test of furniture surface paint film

Before the paint film on the furniture surface ages, the paint film itself can prevent moisture or media from penetrating or can exclude moisture and media. When the paint film ages, it cannot be discharged and gradually accumulates, causing the coating to locally lose adhesion and cause blistering. In high-temperature or high-humidity climates, unqualified paint films are prone to wrinkles, poor adhesion, cracking, and whitening of the paint layer. The moisture and heat resistance test of the paint film on the furniture surface can determine the adaptability of the paint film to the humid and heat environment.
Zhongke Testing Reliability Experiment Center has the capability to test the reliability of various furniture surface paint films, and provides professional reliability testing services such as moisture and heat resistance tests for furniture surface paint film products.

The cured surface of all painted furniture, not suitable for leather furniture and textile furniture surfaces.

Place a heat source block heated to the specified test temperature on a damp cloth in direct contact with the test surface. After the specified test time is reached, remove the heat source block and wet cloth, and leave the test sample for 16 h to 24 h without interference.
Wipe the test surface clean, and check the damage under the specified lighting conditions, such as fading, luster and discoloration, bubbling, swelling, etc. Test results are evaluated using numerical grades.
