Product Description

GUSTAV BERGER'S ORIGINAL FORMULA® 371

A heat-seal adhesive for the lining of paintings,
developed by prof. Gustav Berger in 1970 and universally known
with the name BEVA 371.



Inasmuch as its formula has been copied and not always manufactured with the purest ingredients and without strict adherence to the original formula, professor Berger, in order to prevent any misunderstanding, has renamed his adhesive Gustav Berger’s Original Formula 371.
BEVA 371 (Berger ethylene vinyl acetate) is a product based on ethylenevinylacetate, paraffin, ketone resin, 40% solids content in aliphatic and aromatic solvents.
Gustav Berger’s O. F. 371, used in combination with the special Thinner 372, forms a reversible adhesive with good elasticity and chemical stability. The main application is the hot lining of paintings by using a vacuum hot table (or lining iron and vacuum), but it is also used for fixing minor flakes, for facings and for any kind of temporary or definitive sizing intervention.
