Polymer Coatings Degradation Properties.

摘要

An evaluation of standard paint tests and physical and chemical analysis for naturally and artificially weathered aircraft coatings is reported. Most standard paint tests such as pendulum hardness have little ability to predict coating failure. Physical tests of bulk properties such as dynamic mechanical analysis have little ability to predict coating failure. Surface analysis techniques such as XPS, photoacoustic spectroscopy, and contact angle when used with property data analysis such as Box-Jenkins time series analysis do have predictive and mechanistic utility.
