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).

Primary Capability Area

Materials Characterization and Forensics

Location

Sandia National Laboratories (SNL)

Applications

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.

Availability

These resources are available to SNL scientists and external collaborators.
