Blushing test

Knowledge FAQ
The blushing test is a test method used to evaluate the durability and Appearance of coatings in low temperature environments. In the test, the coated sample is exposed to low temperature conditions, and then the surface is observed for blushing phenomenon to evaluate the low temperature resistance performance and Appearance stability of coatings. This test is very important to determine the performance of coatings in low temperature environments.
