Spectral Fingerprints of Silicone-Based Construction Joint Sealants

November 9, 2020 Science and Technology 0

Silicone is a waterproof polymer used widely to seal joints and voids to prevent leakage of water and air into the building materials. Silicone-based sealant materials are mostly used in the building industry to fill holes and cracks, provide vertical construction projects with water and air tightness, minimise energy consumption bills, and improve the integrity of construction materials. The results of spectral analysis of widely used building sealant materials used in residential and commercial buildings are summarised in this chapter. Using Raman and UV-VIS-NIR spectroscopic techniques, a dozen commercially available silicone-based sealant materials composed of various ingredients representing three producer brands are characterised. Most of the samples tend to have comparable vibrational band assignments and reflectance spectra, it is noted. Analysis of the Raman spectral positions and the reflectance spectrum, however, shows that the sealant materials have distinct variations.
