Aerospace coatings: degradation factors investigated

Monday, 9 July 2012

Australian and US-American researchers investigated the impact of in-service environmental stressors on the durability of exterior decorative aerospace coating systems.

Accelerated weathering was used for a high-gloss polyurethane-based monocoat with and without clearcoat. Colour, gloss, surface roughness, hardness, and chemical composition changes were studied by varying UV irradiance, temperature, thermal extremes, particulate matter and acid environment while using constant moisture condensation conditions.

For the accelerated tests presented in this study, only the highest UV irradiance and temperature level (with or without additional stressors) produced changes in the clearcoat relative to the monocoat system without clearcoat that correlate with in-service performance observations.

The complete study "Investigation of factors impacting the in-service degradation of aerospace coatings” will appear in "Progress in Organic Coatings”, vol. 74, issue 4, August 2012, pp. 679–686.
