DISCOLORATION BY UV STAINING
DISCOLORATION BY UV STAINING
UV staining is a method of evaluating product performance, which is used to detect the discoloration of elastomer material surfaces when exposed to environmental factors such as moisture, humidity, heat, and sunlight. This type of testing is used to help customers develop products that will remain colorfast throughout their lifespan.

One of the main methods used to test for discoloration is ASTM D 1148, which is a standard test method for rubber deterioration heat and ultraviolet light discoloration of light-colored surfaces. This method involves exposing the test material to a combination of heat and ultraviolet light and then measuring the degree of discoloration that is produced. The test results help to determine how resistant the material is to fading and provide an indication of how long it will remain colorfast.
UV staining can also be used to evaluate the performance of products with organic finishes, such as paints and coatings. This type of testing helps to ensure that the products retain their color and finish even after exposure to the elements. UV staining can also be used to detect any changes in the color of products over time, which helps to ensure that they retain their colorfastness and remain vibrant for longer.
