development of rice noodle like glue for historical paintings puts art conservators fears to rest 1234743772
Art conservators faced a crisis after two key ingredients for Beva 371, a glue used to line historical canvases, were discontinued—first the resin Laropal K-80 in 2005 and then the tackifier Cellolyn 21E in 2020. Researchers from the University of Akron and New York University's Conservation Center, funded by a Getty Foundation grant, developed a new version called Beva 371 Akron. The adhesive is less toxic, less vulnerable to supply-chain issues, and available in three forms: a pre-mixed heat-seal variant, solid spaghetti-like pellets for easy transport, and a solvent-free pure adhesive.
