Mechanisms of Military Coatings Degradation: Color and Gloss Performance Evaluation

摘要

The Weapons and Materials Directorate of the Army Research Laboratory (ARL) is leading a research study on military coatings degradation. The goal of this project is to provide detailed analysis of coating system failure mechanisms and where possible provide predictive capability to enable service life estimates for these systems. This interim report focuses on some of the initial durability data gathered on the coatings' exposures in Florida, Arizona and in an accelerated Ultraviolet (UV) light chamber. The changes occurring in the topcoats' camouflage properties (i.e. gloss, color, and infrared reflectance) due to these weathering effects are tabulated and discussed.
