Sun aging test of paint>
Widely used to paint walls, pipes, signs, etc., paint must withstand wind, sun and rain due to the Climate change in nature such as rain, aging, discoloration, cracking and peeling occur after a long time. Therefore, a key factor in determining the quality of paints is the chemical resistance of paints under natural conditions. International The general identification method is to measure the light and to use weather color fastness testing machine to simulate the natural conditions such as sun and rain in the natural environment to accelerate the color aging process, and then evaluate the anti-aging performance of the color according to the test results.

1. Prepare a YG611 color fastness test machine for sunlight and weather.
2. Prepare the test sample, select the standard test sample, spread the paint evenly on the test sample, and wait for the paint to dry completely before using.
3. Place the test pattern in the light and weather color fastness testing machine, start the device and start simulating the natural environment.
4. After a period of time (between 5 and 15 days, depending on actual needs), collect the sample and then compare it with the standard sample to determine the anti-value -Aging behavior of the paint.
