Artwork conservators have been beginning to panic after two crucial elements for a glue known as Beva 371 and used to line historic canvases have been discontinued.
Nevertheless, researchers from the Faculty of Polymer Science and Polymer Engineering at Ohio’s College of Akron (UA) and New York College’s (NYU) Conservation Heart of the Institute of Positive Arts have developed a brand new, safer model of the adhesive. It’s much less prone to supply-chain points, much less poisonous, and is available in varied kinds, together with a solvent-free extrusion that appears like rice noodles.
Beva 371 is an abbreviation for Berger’s Ethylene Vinyl Acetate 371, named after Austrian American conservator Gustav Berger, who died in 2006. He created the glue in 1972, and it was significantly efficient at sticking new canvases to previous ones to shore them up, a course of referred to as “lining.” In contrast to previous glues, it didn’t darken the paint layers by seeping into the unique canvas, so it was extensively adopted within the business.
Paris Via a Window (1913) by Russian French modernist Marc Chagall, which resides on the Solomon R. Guggenheim Museum, was reportedly the primary work from a museum assortment to be handled with Beva 371. Numerous works have benefitted from the glue since.
However after the discontinuation of one in all its key elements in 2005, the resin Laropal Okay-80, there was some trepidation amongst conservators. And when manufacturing of one other important aspect, the tackifier Cellolyn 21E, was halted in 2020, the business actually began to fret. “With out these key resins, a serious useful resource for the sphere of artwork conservation was misplaced,” Ali Dhinojwala, a professor from the Faculty of Engineering and Polymer Science at UA, mentioned in a press release.
Happily, the Getty Foundation’s Conserving Canvas venture handed NYU a analysis grant to develop a brand new adhesive. The college teamed up with UA’s cutting-edge polymer science and plastics engineering programme, and Beva 371 Akron was born.

“Discovering a passable substitute that matched the unique adhesive’s beneficial thermal efficiency was crucial to optimising the fabric choices obtainable to conservators,” Dhinojwala added.
The truth that Beva 371 Akron could be produced in three totally different kinds is one other benefit. They’re a pre-mixed, heat-seal variant like the unique components; a stable, spaghetti-like kind that when minimize into pellets is simpler to move; and soon-to-be launched, pure adhesive, and solvent-free variant.
“We’ve carried out rigorous efficiency testing of the recipe with main specialists, and we’re thrilled with the brand new, conservation-optimised formulation that can present conservators extra methods to work,” Chris McGlinchey, the venture director at NYU and the previous senior conservation scientists on the Museum of Trendy Artwork, mentioned in a press release. “It’s an enormous win anytime you allow a conservator to do their work extra safely and successfully.”
Conservators in Europe labored with the college researchers to develop Beva 371 Akron. “With its advances in supplies innovation and sustainability, the venture is a shining instance of how profitable collaboration could be in a distinct segment business like ours,” Paul Ackroyd, a conservator on the National Gallery in London, mentioned in a press release.
The researchers who developed Beva 371 Akron are presenting their findings this week on the American Institute of Conservation’s yearly convention in Minneapolis.
