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.
A new, tetrafunctional epoxy reactive modifier is increasingly being used as non-mutagenic, drop-in formulation replacement for polyfunctional aziridine.
Formulating pressure-sensitive adhesives (PSAs) presents a number of complex challenges. The adhesive must flow and set without activation from anything more than the pressure of a hand, remain permanently tacky, and exhibit a strong bond—often to a variety of substrates, such as wood, glass, or metal—for as long as the application requires or until the end user decides to remove it.
