Characterization of odors in adhesives

Nowadays almost all products feature adhesives. Some adhesives contain solvents that smell unpleasant. However, solvent-free products or those with a low concentration of solvents can also emit a pungent odor. It is a known fact that adhesives may smell unpleasant. However, as Fraunhofer researchers have recently discovered, this doesn’t need to be the case. Through extensive research on acrylic adhesives they were able to identify 27 substances responsible for the offensive odors. Among other things, the team tested 4 solvent-free acrylic adhesives. They published their research findings in the International Journal of Adhesion and Adhesives (Press Release Fraunhofer, 1 September 2017).
