The wide use of dissimilar substrate materials driving the selection of sealants was reported in The Adhesive and Sealant Council’s “2017-2020 North American Market Report for Adhesives and Sealants with a Global Overview.” Report preparer ChemQuest cited the annual global forecast for sealants in 2020 as 2.8 billion pounds valued at $7.5 billion.
Through 2019, the building and construction market was a sealants volume leader, followed by assembly operations and transportation. Sustainability has led volume growth in the automotive, aerospace, and building construction industries, driven by environmental standards shifting use from solventborne to waterborne adhesives (barring various critical performance end uses that still reportedly require the use of certain solventborne sealants).
