High-Throughput, Anti-Soiling Test Station

DuraMAT's evaluation of anti-soiling coatings requires a consistent, yet rapid, methodology. Controlled deposition with an aqueous suspension of representative soils provides a statistically usable sample set while maintaining reasonably accurate test conditions.

For sample characterization, we use spectral analysis via UV/vis spectroscopy (glass) and quantum efficiency testing (assembled test devices).

Fielded Module Forensics


Sandia National Laboratories (SNL)


The naturally slow process of soil accumulation makes comparative evaluation of anti-soiling coatings difficult. Our process allows for faster evaluation and prototype development. We can also tailor it to suit a specific soil type.


These resources are available to SNL scientists and external collaborators.
