Test method for chemical color aging (i.e., measurement of color retention period)?

2009-02-09View Original

Thread Content

Name of the product manufactured by our company: Adipic Amine**, shape: flake. Chromaticity control is below level 10. In summer, it changes color over a period of 1 month to reach numbers 20-30, while in winter it takes 2-3 months to do so. Sometimes the color code is normal at the time of shipment, but it changes color a week after it arrives at the customer’s place. May I ask which expert has a method for chemical color aging tests (that is, measuring the color retention period)? Thank you!
