Test Background
In a dry and hot environment, the paint film on the surface of unqualified furniture is prone to color separation, loss of gloss, cracking of the primer, and poor adhesion of the paint film. The dry heat resistance test of the furniture surface paint film can determine its adaptability to dry and hot environments.
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 dry heat resistance testing for furniture surface paint film products.
Scope of tests
The cured surface of all painted furniture, not suitable for leather furniture and textile furniture surfaces.
Test method
A heat source block heated to the specified test temperature is placed on the test surface. After the specified test time is reached, remove the heat source block and dry the test area, and leave the test sample for 16 h to 24 h without interference.
Check the damage under specified lighting conditions, such as fading, luster and discoloration, bubbling, swelling, etc. Test results are evaluated using numerical grades.
Test standard:
