Filling the gaps in sealant technology

Andy Extance – Apr 7, 2010

When people are sat cosily at home, they probably don't think about how much of their comfort comes from sealants. However, a selection of innovations from the last year looks set to make buildings and outdoor infrastructure even more weatherproof and long-lasting. High-performance construction sealants are typically based on silicone, polyurea, polysulfide, or polyurethane backbone polymers. Lower-durability sealants and caulks may use an acrylic, vinyl acetate or other water-borne polymer, or a butyl rubber. Higher-performance sealants must be especially durable, remaining solid but flexible under many cycles of extreme temperature and humidity, and avoid damage by ultraviolet light.
