Architectural Materials Analysis
SASAA carries out routine analysis on a wide range of architectural paints and other materials. Sample preparation, photography with low-power microscope and analysis, and imaging with scanning electron microscope with energy dispersive analyser (SEM-EDAX) is carried out to obtain information on composition and method of application. We do not carry out analysis on binders and organic components of paints.
In addition to undertaking full-scale projects, we offer a quick reference analytical facility (Q-RAF), with guaranteed delivery of report within two weeks of receipt of sample.
