Test Background
The expected service life of a decorative coating system from the time it is completed to the time of the first major maintenance application, referred to as durability. The Metal Decorative Coating Durability Test evaluates and grades the durability of decorative coatings on metal surfaces used in construction.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various coatings and provides professional durability testing services for metal surface decorative coatings used in construction.
Test method
metal surface decorative coating can be determined through laboratory accelerated testing, and should meet the specified requirements, and should not exhibit other corrosion and aging phenomena (such as cracking, blistering, peeling, rust, etc.). In case of dispute, the natural environment exposure test results shall prevail.
