Test Background
The xenon arc aging test of paints and varnishes can determine the artificial climate aging test conditions of paints and varnishes exposed to xenon lamp devices, water, and water vapor. The results of aging can be evaluated individually by comparing selected parameters of the coating before, during and after aging.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various paints and varnishes, and provides professional xenon arc aging test services for paints and varnishes.
Scope of tests
Color paint is divided into primer and topcoat: primer is divided into primer, putty, mid-coat, sealer, anti-rust paint, etc.; topcoat is divided into enamel paint, special topcoat, etc.
The paint and film of varnish are transparent and are divided into ester varnish, shellac varnish, phenolic varnish, alkyd varnish, acrylic varnish, polyester varnish, high-performance varnish, fluorocarbon varnish, etc.
Test method
1. Use filtered argon arc light to perform artificial climate aging or artificial exposure to radiation on the coating. The purpose is to cause the coating to undergo a certain degree of change in the selected performance after it is exposed to a certain amount of radiation energy, or to achieve a certain degree of exposure radiation energy required for aging of the coating.
2. The properties selected for monitoring should be those that are important in the actual application of the coating. The performance of an exposed coating can be compared to the performance of a similarly prepared, unexposed coating (comparison sample), or to a coating of known performance that is exposed at the same time (reference sample).
