Polyurea Thick-Film Elastomeric Coating/Lining Systems Accelerated Weatherometer Testing vs. Real Life Exposure

Polyurea Thick-Film Elastomeric Coating/Lining Systems Accelerated Weatherometer Testing vs. Real Life Exposure
Available for download

For years, people have relied upon a variety of industry accelerated testing methods in order to predict how long a coating / lining system may be useful in service. This type of testing would include heat aging, Atlas Cell immersion testing for lining products and accelerated weatherometer testing for coating systems, just to name a few. Polyurea spray applied elastomeric materials have been no exception to this type of testing. One of the most important testing evaluations has been accelerated weatherometer exposure for products used in outdoor application areas.

Polyurea spray applied elastomeric materials have been no exception to this type of testing. One of the most important testing evaluations has been accelerated weatherometer exposure for products used in outdoor application areas. However, much of the data on specific weatherometer testing may in fact be misleading and exaggerated to a point. There have been some observations that exposure to a given number of hours of accelerated exposure, points to a specific number (often high) of years of real-time field performance service without any comparative data. This paper will compare earlier Accelerated Weatherometer Testing (QUV) to real time outdoor exposure on spray applied polyurea elastomeric coating / lining systems.

The practice of lining concrete substrates has increased exponentially over the past thirty (30) years, most notably in the wastewater treatment industry. Environmental regulations, coupled with changes to treatment processes, have resulted in far more severe environments in which concrete can and will corrode.

New high-solids coatings are sometimes required to meet volatile organic compound (VOC) legislation. Lack of data on same needs accelerated test methods to evaluate performance. The test method must: • Be performed using commercially available equipment • Take a relatively short time period. • Correlate with real life exposure.
