Adhesives are often a better way to assemble plastics than by using mechanical assembly with fasteners. For example, fiberglass composites are routinely bonded with epoxy or reactive acrylic adhesives in the automotive and marine industries because they give high strength and durable bonds.
This weekly roundup highlights the adhesives, sealants and coatings news stories that garnered the most attention during the previous week on our website, as well as our eNewsletter and social media platforms.
